Understanding Scuba Wetsuits: Key Features and Technologies
A properly fitted wetsuit provides both warmth and flexibility underwater
Before diving into specific product recommendations, it’s essential to understand what makes a quality scuba wetsuit and how different features affect performance underwater.
Neoprene Types and Quality
The foundation of any wetsuit is its neoprene material. Modern wetsuits utilize several advanced neoprene variations:
- Standard Neoprene: The traditional material used in most entry-level wetsuits. Provides good insulation but may be less flexible.
- Super-Stretch Neoprene: Enhanced with additional elastic fibers, these materials (like Yamamoto neoprene) offer superior flexibility and range of motion.
- Limestone-Based Neoprene: An eco-friendly alternative to petroleum-based neoprene, offering similar thermal properties with reduced environmental impact.
- Infrared/Thermal Lined Neoprene: Features special interior linings (like Bare’s Omnired or Fourth Element’s thermocline) that reflect body heat for enhanced warmth.
Wetsuit Thickness Options
Wetsuit thickness, measured in millimeters, directly correlates with thermal protection. The thickness is often expressed with two numbers (e.g., 5/4mm), indicating different thicknesses in various areas of the suit.
| Thickness | Water Temperature | Suitable For |
| 1-2mm | 85°F+ (29°C+) | Tropical waters, very warm conditions |
| 3mm | 75-85°F (24-29°C) | Warm water diving, tropical locations |
| 5mm | 65-75°F (18-24°C) | Moderate temperatures, versatile option |
| 7mm | 50-65°F (10-18°C) | Cold water diving |
| 8-9mm | Below 50°F (Below 10°C) | Very cold water (consider a drysuit) |
Seam Construction
The way a wetsuit’s seams are constructed significantly impacts both warmth and durability:
Overlock Stitched
The most basic and least expensive construction. Neoprene panels are overlapped and stitched together. Water can penetrate through the stitch holes, making these suits less suitable for colder water.
Flatlock Stitched
Panels are butted together and stitched flat. More comfortable than overlock but still allows water penetration. Ideal for warmer water (above 65°F/18°C).
Glued and Blind Stitched (GBS)
Panels are glued together and then stitched without penetrating through the entire material. Minimizes water entry and provides better insulation for colder waters.
Sealed Seams
GBS seams with additional liquid sealing tape or rubber applied over the stitching. Offers maximum waterproofing for cold water diving.
Zipper Types and Placement
Wetsuits feature different zipper configurations, each with advantages:
- Back Zip: Traditional design with a zipper running down the back. Easier to don/doff but may allow more water flushing.
- Chest Zip: Horizontal zipper across the chest. Better water seal but can be more challenging to put on.
- Front Zip: Vertical zipper down the front. Easier to put on without assistance but may compromise water seal.
“The perfect wetsuit should feel like a second skin—snug but not restrictive. When properly fitted, it should be challenging to put on when dry but feel natural and comfortable once in the water.”

How to Choose the Right Scuba Wetsuit: Buying Considerations
Professional fitting at a dive shop can help ensure you select the right size wetsuit
Selecting the perfect wetsuit involves considering several key factors beyond just brand and price. Here’s what to evaluate when making your decision:
Fit: The Most Critical Factor
A properly fitted wetsuit should be snug but not restrictive. When trying on a wetsuit, check for:
- No gaps or loose areas, especially around the small of the back, underarms, and crotch
- Snug collar that lies flat against your neck without choking
- Wrist and ankle seals that fit tightly without cutting off circulation
- No excess material bunching at joints or extremities
- Ability to squat and raise arms without extreme resistance
“When fitting a wetsuit, remember that it will feel tighter on land than in water. If you can pinch more than an inch of material anywhere, especially at the lower back or under the arms, the suit is too large. A proper fit should feel almost uncomfortably snug when dry but will relax slightly when wet.”
Temperature Range vs. Thickness
Match your wetsuit thickness to the water temperatures you’ll encounter most frequently:
| Water Temperature | Recommended Thickness | Suit Type |
| 85°F+ (29°C+) | 0.5-2mm | Skin, shorty, or rash guard |
| 75-85°F (24-29°C) | 2-3mm | Full suit or shorty |
| 65-75°F (18-24°C) | 3-5mm | Full suit |
| 55-65°F (13-18°C) | 5-7mm | Full suit with hood |
| 45-55°F (7-13°C) | 7mm or semi-dry | Full suit with hood, gloves, boots |
| Below 45°F (Below 7°C) | Drysuit recommended | Drysuit with appropriate undergarments |
Pro Tip: Consider the depth of your dives when selecting thickness. Neoprene compresses at depth, reducing both buoyancy and thermal protection. If you regularly dive deeper than 60ft/18m, you might want to choose a slightly thicker suit than the temperature chart suggests.
Flexibility vs. Warmth: Finding the Balance
There’s often a tradeoff between thermal protection and range of motion. Consider your diving style:
Prioritize Warmth If:
- You tend to get cold easily
- You plan longer bottom times
- You’ll be diving in variable conditions
- You’re diving in areas with thermoclines
- You prefer a more relaxed diving style
Prioritize Flexibility If:
- You’re diving in consistently warm waters
- You’re an underwater photographer
- You need maximum mobility for technical diving
- You plan to use your suit for multiple water activities
- You have a more active diving style
Additional Features to Consider
- Reinforced Knee Pads: Essential if you frequently kneel on the bottom or enter from rocky shores
- Spine Pad: Provides cushioning against tank pressure
- Wrist/Ankle Zippers: Make donning and doffing easier, especially with thicker suits
- Hood (Attached or Separate): Critical for cold water diving
- Pockets: Convenient for carrying small accessories
- Computer Mounting Pad: Prevents dive computer from sliding on your wrist
Wetsuit Care and Maintenance
Proper care extends the life of your wetsuit and maintains its performance. Follow these essential maintenance tips:
After Each Dive
- Rinse thoroughly with fresh water (inside and out)
- Turn inside-out and rinse again
- Hang to dry on a wide, padded hanger away from direct sunlight
- Once exterior is dry, turn right-side out to dry the interior
- Ensure completely dry before storage to prevent mildew
Deep Cleaning (Monthly)
- Fill a tub with cool water
- Add wetsuit-specific cleaner (avoid detergents)
- Submerge suit and gently agitate
- Let soak for 15-20 minutes
- Rinse thoroughly with fresh water
- Hang to dry as usual
Storage Tips
- Store on a wide, padded wetsuit hanger
- Keep in a cool, dry place away from direct sunlight
- Avoid folding for long periods to prevent creases
- Don’t store in compressed spaces like car trunks
- If storing long-term, lightly dust with talcum powder to prevent sticking
What to Avoid
- Never machine wash or dry
- Avoid petroleum-based products (they degrade neoprene)
- Don’t use hangers that create pressure points
- Avoid prolonged exposure to chlorine
- Don’t use fingernails when donning (they can puncture neoprene)
Wetsuit Sizing Guide
Finding your correct wetsuit size can be challenging, as sizing varies between manufacturers. Here are general guidelines to help you find the right fit:
How to Measure
Key measurement points for proper wetsuit sizing
Take the following measurements while wearing thin, form-fitting clothing:
- Height: Stand straight with feet together
- Weight: Use a recent, accurate measurement
- Chest/Bust: Measure at the widest point, keeping the tape parallel to the floor
- Waist: Measure at the narrowest point, usually at the navel
- Hips: Measure at the widest point around your buttocks
- Inseam: Measure from crotch to ankle bone
Important: When between sizes, consider your body type. If you have an athletic build with broader shoulders or chest, size up. If you have a slimmer build, size down for a snugger fit.
Women’s vs. Men’s Wetsuits
Women’s and men’s wetsuits are cut differently to accommodate different body shapes:
Women’s Wetsuits
- More room in chest/bust area
- Narrower at shoulders
- More defined waist
- Wider at hips
- Often shorter in torso length
Men’s Wetsuits
- Broader at shoulders
- Straighter cut through torso
- Less room in hip area
- Often longer in torso and limbs
- More room in chest and shoulders
Always refer to the manufacturer’s specific sizing chart, as there can be significant variation between brands. When possible, try on wetsuits before purchasing or order from retailers with good return policies.
Frequently Asked Questions About Scuba Wetsuits
How long should a quality scuba wetsuit last?
With proper care and maintenance, a quality scuba wetsuit should last 200-300 dives or approximately 4-7 years of regular use. Factors affecting longevity include frequency of use, exposure to sunlight, proper rinsing/drying, and storage conditions. Higher-end wetsuits with better seam construction and more durable neoprene typically last longer than budget options.
Should I wear anything under my wetsuit?
For comfort and hygiene, many divers wear a thin base layer under their wetsuit. Options include:
- Rash guards or compression shirts
- Thermal base layers for additional warmth
- Lycra shorts or swimwear
These layers help prevent chafing and make the wetsuit easier to don and doff. For cold water diving, specialized thermal undergarments can significantly enhance warmth.
How do I know if my wetsuit fits correctly?
A properly fitted wetsuit should:
- Feel snug but not restrictive
- Have no loose or baggy areas, especially in the lower back, underarms, and crotch
- Allow you to squat and raise your arms overhead (with some resistance)
- Have seals that fit tightly at wrists and ankles without cutting off circulation
- Have a collar that lies flat against your neck without choking
Remember that wetsuits loosen slightly in water, so a suit that feels almost too tight on land may be perfect underwater.
What’s the difference between a wetsuit and a semi-dry suit?
While both use neoprene for insulation, semi-dry suits incorporate additional features to minimize water entry and exchange:
- Wetsuits allow a thin layer of water to enter, which is then warmed by body heat
- Semi-dry suits use improved seals at wrists, ankles, and neck, plus waterproof zippers to reduce water entry and flushing
Semi-dry suits typically offer better thermal protection than wetsuits of the same thickness but are more expensive and less flexible. They’re ideal for cold water diving where a drysuit might be excessive.
How do I repair small tears or holes in my wetsuit?
Small repairs can be made using neoprene cement or specialized wetsuit repair kits:
- Clean and dry the damaged area thoroughly
- For tears, apply neoprene cement to both edges and press together
- For holes, apply a neoprene patch with cement
- Allow to cure for 24 hours before using
For larger damages or repairs to critical seams, consider professional repair services offered by many dive shops or wetsuit manufacturers.
Can I use the same wetsuit for different water activities?
While possible, scuba wetsuits are specifically designed for diving conditions:
- Scuba wetsuits are typically thicker, with reinforced seams and specialized features for depth and pressure changes
- Surfing wetsuits prioritize flexibility and often have reinforced knee pads for paddling
- Swimming/triathlon wetsuits focus on hydrodynamics and shoulder flexibility
For occasional crossover use, a scuba wetsuit can work for other activities, but dedicated athletes in each sport will benefit from sport-specific designs.
Final Thoughts: Investing in Your Underwater Comfort
Choosing the best scuba wetsuit is a personal decision that depends on your specific diving conditions, body type, and preferences. While premium features and materials do come at a higher price point, a quality wetsuit is an investment in your comfort, safety, and enjoyment underwater.
Remember that proper fit is the most critical factor—even the most expensive wetsuit will perform poorly if it doesn’t fit correctly. When possible, try before you buy or purchase from retailers with good return policies.
By understanding the key features, maintaining your wetsuit properly, and selecting the right thickness for your diving environment, you’ll ensure many comfortable and warm dives for years to come.
