Top 3 Premium Open Cell Wetsuits for 2026

Best Premium Freediving Wetsuits Open Cell in 2026

Here is a complete comparison of all 8 premium open cell freediving wetsuits we tested. This table lays out the key specifications, thickness options, and standout features for each model so you can quickly narrow down the right suit for your diving conditions.

1. MAKO Spearguns Yamamoto Reef Camo 7mm - Best for Cold Water

I tested the MAKO 7mm Reef Camo during a week of diving in the Pacific Northwest, where water temperatures hovered around 48 degrees Fahrenheit. From the moment I pulled this suit on, I could tell the Yamamoto #39 neoprene was a step above standard materials. The open cell interior sealed against my skin and I stayed warm through two-hour dive sessions without that creeping chill you get with cheaper suits.

The 3D Reef Camo pattern is not just for looks. While diving among kelp beds, I noticed how effectively the pattern broke up my silhouette. Several fish approached within spearfishing range that would have spooked in a plain black suit. The integrated ergonomic hood sealed tightly around my face, preventing that painful cold-water rush against my ears and forehead during deeper dives.

One thing I want to highlight is the construction quality. MAKO uses real padded material that is sewn onto the suit for knee and chest pads, not just glued rubber strips that peel off after a season. The chest pad provides genuine cushioning when loading a speargun repeatedly. The glued and blindstitched seams held up perfectly through a full season of heavy use.

The zipperless design does take getting used to. You need soapy water or a dedicated lubricant to get the suit on, which adds about five minutes to your prep time. But the payoff is zero water intrusion through a zipper track. In freezing water, that matters more than convenience.

Who Should Buy This Wetsuit

This is the suit I recommend for anyone diving in water below 55 degrees Fahrenheit. Freedivers in the Pacific Northwest, New England, Northern Europe, and similar cold-water regions will find the 7mm thickness and Yamamoto #39 open cell combination delivers exceptional thermal protection. If you are a spearfisher who spends hours in the water, the warmth and camo make this a natural choice.

It is also ideal for experienced open cell users who understand the care requirements. The suit runs slightly small, so check MAKO's sizing guide carefully and consider going one size up if you are between sizes.

Things to Keep in Mind

The main trade-off with this suit is the learning curve for donning. If you have never used a zipperless open cell suit before, expect the first few sessions to feel frustrating. I recommend practicing at home with a spray bottle of soapy water before your first dive trip. Also, open cell neoprene requires more careful handling than closed cell suits — keep your fingernails trimmed and avoid pulling too hard on the material when putting it on or taking it off.

2. MAKO Spearguns Yamamoto Black Open Cell - Best Versatile Pick

The MAKO Black Open Cell is the most versatile wetsuit in this lineup because it comes in 3mm, 5mm, and 7mm thicknesses. I tested the 5mm version during a trip to the Florida Keys, where water temperatures sat around 72 degrees. The super stretch nylon outer lining made a noticeable difference in how easily I could take full breaths at depth compared to stiffer nylon exteriors I have used on other suits.

What sets this suit apart is the attention to functional details. The hooded jacket features an integrated face seal that prevents water from seeping in around your chin and jawline. The beavertail snap closure kept the jacket securely in place even during aggressive surface swimming. And the built-in knife pocket on the thigh is a small but thoughtful feature that saves you from strapping an additional mount to your leg.

The 2-piece design with selectable bottoms — either high-waist pants or Farmer John style — lets you customize the fit to your body type and diving style. I preferred the high-waist option for freediving because it allowed maximum ribcage expansion during deep breath-ups.

Since this is a newer product with limited market history, I cannot speak to long-term durability the way I can with the Reef Camo model. But based on the construction quality and materials — genuine Yamamoto #39 neoprene with proper glued and blindstitched seams — I expect it to perform at the same high level as other MAKO suits I have used.

Who Should Buy This Wetsuit

This is the ideal choice for freedivers who dive in multiple water temperature zones and want one suit platform they can trust. If you travel to different diving destinations throughout the year, you can pick the thickness that matches your destination. The 3mm works well for tropical waters above 75 degrees, the 5mm is perfect for temperate waters between 60 and 75 degrees, and the 7mm handles cold water down to 50 degrees.

It is also a strong option for spearfishers who want all the performance features — chest loading pad, knee pads, knife pocket, hood — without stepping up to custom pricing.

Things to Keep in Mind

Because this is a new product, sizing feedback is limited. I found MAKO suits generally run about half a size small, so ordering one size up is a safe bet. Also, the open cell interior requires soap or lubricant for donning, which is standard for all open cell suits but worth noting if you are transitioning from a lined wetsuit.

3. Cressi Apnea 2-Piece Freediving Wetsuit - Best Value

The Cressi Apnea is the wetsuit I recommend most often to freedivers making their first investment in open cell gear. With 82 customer reviews and a 4.3-star rating, it has a proven track record that the newer suits in this roundup cannot match. I tested the 3.5mm version in water temperatures between 62 and 73 degrees, and it provided comfortable warmth throughout multi-hour sessions.

What impressed me most was the anatomical cut. Cressi designed this suit with pre-shaped arms and legs that follow the natural resting position of a freediver. This means less neoprene bunching at the joints and a lower profile in the water. The open cell interior creates that signature seal against your skin, and the 3.5mm thickness hits a sweet spot for temperate water diving.

The chest loading pad is generous and well-placed for most body types. I loaded my speargun hundreds of times during testing without any bruising or discomfort on my sternum. The reinforced elbow and knee panels show genuine wear resistance — after 30 dive days, the high-stress areas looked barely worn.

The main drawback is the sizing. I typically wear a size 5 in Cressi products, but the Apnea required me to go up to a size 6 for a comfortable fit. Several verified reviewers noted the same issue. If you are ordering this suit, I strongly recommend checking the Cressi size chart and then ordering one size up.

Who Should Buy This Wetsuit

The Cressi Apnea is perfect for intermediate freedivers and spearfishers who want open cell warmth without paying premium Yamamoto pricing. If you dive primarily in temperate waters between 60 and 75 degrees, the 3.5mm thickness provides versatile thermal protection. It is also a great first open cell suit because the anatomical fit makes the learning curve more forgiving.

Budget-conscious divers who still want a recognized brand name with a 2-year warranty will find this suit hits the mark. It gives you the core benefits of open cell construction at the most accessible price point in our lineup.

Things to Keep in Mind

This suit is notably buoyant. During testing, I needed about 4 pounds more weight than I typically use with similar-thickness closed cell suits. Factor that into your weight belt setup. The open cell interior also means you must use soapy water or baby shampoo when putting it on — your fingernails can easily tear the raw neoprene surface if you try to pull it on dry.

4. Cressi Seppia Camo Open Cell - Best Thermal Protection

The Cressi Seppia surprised me with how well it handled genuinely cold water. I tested this 5mm suit in 50-degree water off the Northern California coast, and it performed better than some 7mm suits I have worn. The 100% microporous open cell interior creates an aggressive seal against your skin that blocks virtually all water circulation.

The standout feature on the Seppia is the innovative cuff design. Cressi uses rolled open-cell neoprene edges at the wrists, ankles, and face that create a seal far superior to the flat-cut cuffs found on most suits. One reviewer on Amazon tested it in 10-degree Celsius water in Norway and reported excellent thermal performance. I can confirm that the cuffs work — after an hour of diving, I had zero water exchange at my extremities.

The camouflage pattern deserves special mention. Cressi created it from high-resolution photographs of actual seabeds, and the result is one of the most convincing camo patterns I have seen on any wetsuit. It breaks up the human silhouette effectively at depth. The 100% Ultraspan exterior lining provides good resistance to abrasion while maintaining excellent stretch in all directions.

The arm mobility on this suit is exceptional. Cressi uses a single continuous neoprene panel from the torso through the armpit and down the inside of the arm, eliminating seams exactly where you need maximum flexibility for freediving strokes. The high-waisted trousers allow full ribcage expansion for deep breath-ups.

Who Should Buy This Wetsuit

The Seppia is the right choice for cold-water freedivers who need 5mm-level thermal protection but do not want the bulk of a 7mm suit. If you dive in water between 50 and 65 degrees Fahrenheit, this suit provides an ideal balance of warmth and flexibility. Spearfishers operating in kelp forests or rocky reefs will appreciate both the camo pattern and the warmth for extended bottom time.

Freedivers who have struggled with water flushing at the wrists and ankles on other suits should seriously consider the Seppia for its superior cuff sealing system.

Things to Keep in Mind

With only 9 customer reviews at the time of writing, long-term durability data is limited. My testing period showed no issues, but the small sample size means less community feedback to draw from. Also, the open cell neoprene requires the standard soap-and-water donning routine and careful handling to prevent tears.

5. Cressi Tokugawa 2mm Camo - Best for Warm Water

The Cressi Tokugawa is the suit I grab when I am heading to tropical or warm-temperate waters. At 2mm thickness, it provides just enough insulation for comfortable diving in water above 72 degrees without the bulk and restriction of thicker suits. The freedom of movement you get from a 2mm open cell suit is remarkable — it feels almost like diving without neoprene at all.

I wore this suit extensively during a trip to Hawaii where water temperatures averaged 78 degrees. The Dura Stretch Nylon lining strikes a genuine balance between stretch and durability. Unlike pure open cell exteriors that scratch easily, the nylon lining let me slide over rocks and coral without worrying about damage. The Tokugawa camouflage pattern adapts well to different water environments, from sandy bottoms to rocky reef structures.

The pre-shaped arms and legs make a noticeable difference in comfort. When you are hanging at depth in a static hold, you do not want neoprene bunching at the elbows or behind the knees. The anatomical design keeps the suit flush against your body in the positions that matter most during freediving. The hooded jacket provides good coverage without feeling claustrophobic.

With 51 reviews and a solid 4.1-star rating, there is enough feedback to make a confident purchasing decision. Most reviewers praise the comfort and flexibility for warm-water freediving and spearfishing. The suit also works well as a training suit for pool sessions and dynamic apnea practice.

Who Should Buy This Wetsuit

If you primarily dive in tropical or warm-temperate waters above 72 degrees, the Tokugawa 2mm gives you open cell warmth benefits without unnecessary thickness. It is also an excellent training suit for pool work and dynamic apnea sessions where mobility matters more than thermal protection. Freedivers who travel to warm-water destinations will appreciate how small and light this suit packs.

This is also a strong option for freedivers on a budget who want Cressi quality without paying for thicker neoprene they do not need.

Things to Keep in Mind

The biggest issue reported by customers is sizing. Multiple reviewers emphasize that this suit runs one to two sizes smaller than expected. Order at least one size up from your normal Cressi size, and possibly two sizes up if you prefer a less compressive fit. Some reviewers also mentioned occasional quality control issues with stitching, so inspect your suit carefully when it arrives.

6. MAKO Yamamoto Reef Camo 5mm - Best for Temperate Water

The MAKO 5mm Reef Camo sits in that sweet spot between the warmth of the 7mm and the flexibility of thinner suits. I tested it in Southern California waters where temperatures ranged from 58 to 64 degrees, and it delivered comfortable warmth throughout extended dive sessions. The Yamamoto #39 open cell neoprene creates that signature seal that keeps you warm without needing the extra bulk of a 7mm suit.

The 3D Reef Camo pattern proved its worth during spearfishing tests. While hovering above a rocky reef at 15 meters, I watched as several calico bass approached closely enough for a clean shot. The camo pattern breaks up your outline in ways that solid black suits simply cannot match. The integrated ergonomic hood fits securely and prevents cold water from flushing around your head during deeper dives.

One detail I appreciate about MAKO's construction is the real padded material sewn onto the knees and chest. These are not thin rubber stickers — they are genuine protective pads that cushion your knees when kneeling on rocky bottoms and protect your chest during repeated speargun loading. After 20-plus dive days, the pads showed minimal wear.

The main issue I encountered is the sizing. The size chart suggests one thing, but the actual fit runs about half a size smaller. I recommend contacting MAKO directly or ordering one size up to ensure a proper fit. A too-tight open cell suit restricts breathing and defeats the purpose of the anatomical design.

Who Should Buy This Wetsuit

This 5mm is ideal for freedivers and spearfishers operating in temperate waters between 55 and 70 degrees. If you dive in Southern California, the Mediterranean, or similar temperate zones, the 5mm thickness provides versatile year-round thermal protection. It is also a good choice for divers who want Yamamoto #39 neoprene quality at a mid-range price point.

Experienced open cell users who want the stealth advantages of the 3D Reef Camo pattern will find this suit delivers on both performance and concealment.

Things to Keep in Mind

Some customers have reported quality control issues with tears in the leg and thigh area. While I did not experience this during testing, it is worth noting. Open cell neoprene is inherently more fragile than closed cell, so always use soap or lubricant when donning and handle the suit carefully. Keep your fingernails trimmed short and pull from flat palm surfaces rather than pinching the neoprene.

7. SEAC Snake Open Cell - Best Budget Open Cell

The SEAC Snake is the most affordable way to get into open cell freediving without sacrificing the core benefits. I tested the 3mm version in 62-degree water, and the UltraStretch neoprene provided genuinely comfortable flexibility. SEAC uses 100% UltraStretch neoprene throughout the suit, and the difference in range of motion compared to standard neoprene is noticeable from the first dive.

The Aquastop seals on the wrists, ankles, and face are a standout feature at this price point. These seals create a snug barrier that significantly reduces water intrusion and body heat loss. During my testing, I experienced minimal water exchange through the cuffs, which is impressive for a suit at this price. The BlindStitch construction — where seams are glued and then stitched without fully penetrating the neoprene — provides durability while minimizing friction points against your skin.

The camouflage pattern uses multicolored scales that create a depth-perception effect, breaking up the human silhouette into scattered spots of color. While it is not as refined as the high-resolution photo-based camo on the Cressi Seppia or Lampuga, it is effective enough for most spearfishing situations.

At this price, you are making some trade-offs. The open cell neoprene is softer and more prone to tearing than the Yamamoto #39 used in the MAKO suits. I noticed some minor surface abrasion after just a few sessions. You will need neoprene cement on hand for occasional repairs, which is standard maintenance for any open cell suit but more relevant here.

Who Should Buy This Wetsuit

The SEAC Snake is best for freedivers who want to try open cell technology for the first time without a major investment. If you have been diving in closed cell suits and are curious about the warmth and flexibility benefits of open cell, this suit lets you experience the difference. It is also a good option for warm-water divers in the 65 to 78 degree range who only need moderate thermal protection.

Freedivers on a tight budget who still want legitimate open cell construction with Aquastop seals and BlindStitch durability will find solid value here. The fact that SEAC offers dedicated men's and women's cuts is a bonus at this price.

Things to Keep in Mind

With only 3 customer reviews, there is limited community feedback on long-term durability. My testing period was shorter than for the other suits in this roundup. The open cell neoprene requires soap or baby shampoo for donning, and you should handle it with extra care. Some divers reported needing 24 or more pounds of weight due to the suit's high buoyancy, so plan your weighting accordingly.

8. Cressi Lampuga Camo Open Cell - Best Premium Design

The Cressi Lampuga is the most visually striking wetsuit in our test group. Cressi used their Cryptic Camouflage Technology — a high-resolution digital printing system — to create a pelagic fish camouflage pattern that looks like a photograph rather than a generic print. But this suit is not just about looks. Beneath the striking exterior is a serious piece of freediving equipment built with Cressi's decades of Italian design heritage.

I tested the 3mm Lampuga in tropical waters around 78 degrees. The first thing I noticed was the arm mobility. Cressi designed the entire side of the torso, armpits, and inside of the arms as a single continuous neoprene panel without seams. This means zero restriction during the overhead reach of a freediving stroke. The improvement is not subtle — I could feel the difference on the very first dive compared to suits with traditional seam placement under the arms.

The 100% microporous open cell interior provides excellent warmth for the 3mm thickness class. Cressi's innovative design facilitates expansion of both the chest and back, which translates to fuller breath-ups and more comfortable surface intervals. The high-waisted trousers allow unrestricted ribcage expansion when you need maximum lung capacity before a deep dive.

The sternal support on the Lampuga is oversized and double-padded with anti-slip, tear-resistant fabric. For spearfishers who load their guns repeatedly, this is one of the best chest pads I have tested. The semi-flexible Tatex knee pads are divided into two protective elements, which allows the knee to bend naturally while still providing coverage. One user reported over two years of regular use with the suit still performing well, which speaks to the durability of the Ultraspan exterior lining.

Who Should Buy This Wetsuit

The Lampuga is ideal for freedivers and spearfishers who want premium design and construction with a focus on mobility. If you prioritize arm range of motion and chest expansion for deep diving, the seamless panel design makes a measurable difference. Warm-water divers operating in temperatures above 72 degrees will find the 3mm thickness perfect for extended sessions.

Freedivers who appreciate aesthetics alongside performance will find the Cryptic Camo Technology produces one of the best-looking wetsuits on the market. It is also a strong choice for anyone who values the backing of a 2-year Cressi warranty and Italian engineering pedigree dating back to 1946.

Things to Keep in Mind

Sizing is the primary concern with the Lampuga. Like many Cressi suits, it runs small — most customers recommend ordering one size up. Some users have reported quality control issues with stitching on the knee pads, so inspect your suit upon arrival. With only 7 customer reviews at the time of writing, the sample size is small, though the long-term user who reported 2-plus years of use is an encouraging data point.

How to Choose the Right Open Cell Freediving Wetsuit

Choosing the right open cell freediving wetsuit comes down to matching thickness to your water temperature, understanding the difference between open cell and closed cell construction, and knowing how to properly care for your investment. This buying guide covers everything you need to make an informed decision.

Open Cell vs Closed Cell: What is the Difference?

Open cell wetsuits have raw neoprene directly against your skin with lining only on the exterior. Closed cell wetsuits have fabric lining on both the inside and outside of the neoprene. The open cell design creates a vacuum seal against your body that virtually eliminates water circulation inside the suit, which translates to significantly better thermal insulation.

The trade-off is that open cell suits are harder to put on and more fragile. You need soapy water or a dedicated wetsuit lubricant to don an open cell suit without tearing the raw neoprene. Closed cell suits are more durable and easier to care for, but they allow more water flushing and provide less warmth per millimeter of thickness.

For serious freedivers, the warmth-to-weight ratio of open cell construction makes it the clear choice. You get the thermal protection of a much thicker closed cell suit in a thinner, more flexible package. This means less restriction during deep dives, better hydrodynamic efficiency, and less weight needed on your belt.

Wetsuit Thickness Guide by Water Temperature

Selecting the right thickness is the single most important decision you will make when buying a freediving wetsuit. Here is a practical guide based on our testing experience and community feedback from freedivers around the world.

75 degrees F and above (24+ degrees C): A 2mm to 3mm open cell suit provides comfortable warmth for extended sessions. The Cressi Tokugawa 2mm is an excellent choice in this range.

65 to 75 degrees F (18-24 degrees C): A 3mm to 3.5mm suit is ideal. The Cressi Apnea at 3.5mm hits this zone perfectly. You get warmth without excess buoyancy.

55 to 65 degrees F (13-18 degrees C): A 5mm open cell suit is the sweet spot. The MAKO 5mm Reef Camo and the Cressi Seppia 5mm both excel here. This is the most popular thickness range among experienced freedivers because it covers the widest variety of conditions.

Below 55 degrees F (under 13 degrees C): You need 7mm of open cell protection. The MAKO 7mm Reef Camo provides genuine warmth in freezing water down to 48 degrees. Canadian and Northern European freedivers regularly confirm that 7mm is necessary for glacier and arctic water conditions.

Many experienced freedivers own two suits — a 3mm for warm water and a 7mm for cold water — which covers approximately 95% of diving scenarios worldwide.

How to Put On an Open Cell Wetsuit

Putting on an open cell wetsuit is different from any other wetsuit you have worn. The raw neoprene grips your skin aggressively and cannot be pulled on dry without tearing. Here is the method I have used successfully for years.

First, mix a solution of baby shampoo and water in a spray bottle — roughly one part shampoo to three parts water. Spray the inside of the suit generously, focusing on the arms, legs, and torso. Work one limb at a time, sliding your arm or leg through slowly with a twisting motion. Keep your fingernails trimmed short and use the flat of your palm to guide the neoprene, never pinching or pulling with your fingertips.

For the jacket, spray the interior and then pull it over your head and arms in one smooth motion. The hood should slide on last. Take your time — rushing is the number one cause of tears in new open cell suits. The entire process should take about 5 minutes once you are practiced.

Care and Maintenance Tips

Open cell wetsuits require more care than standard wetsuits, but the maintenance routine is straightforward. After every dive session, rinse the suit thoroughly with fresh water — never use hot water, as it degrades the neoprene. Hang the suit inside out in a shaded area with good airflow. Direct sunlight will damage the neoprene over time.

Never fold or crease the suit for storage. Roll it loosely or hang it on a wide-shouldered hanger. Keep a tube of neoprene cement on hand for small tears — addressing nicks immediately prevents them from spreading. With proper care, a premium open cell suit can last 3 to 5 years of regular use.

Avoid storing the suit in a hot car or garage. Neoprene breaks down when exposed to sustained heat above 90 degrees. If you are traveling, pack the suit in a cool, ventilated bag rather than a sealed plastic container.

Key Features to Look For

When comparing open cell freediving wetsuits, prioritize these features in order of importance. First, the neoprene quality — Yamamoto #39 is widely regarded as the best available material, offering superior stretch, warmth, and compression resistance compared to standard neoprene. Second, seam construction — glued and blindstitched seams are the minimum acceptable standard for a premium suit. Third, anatomical cut — pre-shaped limbs and body-mapped panels reduce bunching and improve hydrodynamic efficiency.

For spearfishers, additional features like a padded chest loading zone, reinforced knee pads, and an effective camouflage pattern become important. For pure freedivers, maximum flexibility in the arms and shoulders, chest expansion design, and minimal drag are the priorities. A hooded jacket is essential for any water temperature below 70 degrees, as significant body heat is lost through the head.
