Common questionsFrequently asked questions

What thickness wetsuit do I need?

Thickness depends on water temperature. For 65-75°F, a 3/2mm is ideal. For 55-65°F, a 4/3mm is recommended. Below 55°F, consider a 5/4mm or hooded suit. For warm water above 75°F, a shorty or 2mm is sufficient.

How should a wetsuit fit?

A wetsuit should be snug but not restrictive. It should not have excess material or gaps, especially around the neck, wrists, and ankles. If it's too loose, water will flush in and reduce warmth. If too tight, it can restrict breathing and movement.

What is the difference between back zip, chest zip, and front zip?

Back zip is traditional and easy to put on but can leak. Chest zip reduces water entry and offers better flexibility but is harder to don. Front zip combines convenience with a good seal, often found in high-end suits.

How do I care for my wetsuit?

Rinse with fresh water after each use, dry in the shade away from direct heat, and hang on a wide hanger to avoid stretching. Avoid folding or storing in a tight space. Use a wetsuit shampoo occasionally to remove odors.

Buying guideHow to choose

Consider Water Temperature

The most important factor is the water temperature you'll be in. Thicker suits provide more warmth but reduce flexibility. Choose a thickness that matches your typical conditions.

Activity Type

Surfing requires flexibility and durability, diving needs thickness and warmth, and triathlon suits prioritize buoyancy and ease of movement. Pick a suit designed for your primary activity.

Fit and Comfort

A proper fit is crucial. Try on different brands as sizing varies. Look for a suit that is snug without being restrictive. Check for any gaps or discomfort, especially in the shoulders and neck.

At a glanceFeatures compared

FeatureWhy it matters
Neoprene QualityHigh-quality neoprene like Yamamoto or TechnoButter offers better flexibility, warmth, and durability. It directly impacts comfort and performance.
Seam ConstructionGlued and blind-stitched (GBS) seams are waterproof and durable. Flatlock seams are less waterproof but more flexible. For cold water, GBS is essential.
Zip TypeChest and front zips provide better seal and flexibility than back zips. They reduce water flush and are preferred for performance, though they can be harder to put on.
Thermal LiningInternal linings like thermal fleece or titanium enhance warmth without adding bulk. They are key for cold-water suits and improve comfort.
