Best Wetsuits for Warmth, Stretch and Fit (2026)
Five wetsuits from value back-zips to premium stretchy chest-zips, a water-temperature thickness chart and how to get the fit right.
How a Wetsuit Keeps You Warm
A wetsuit traps a thin layer of water against your skin, which your body warms, while the neoprene insulates you from colder water outside. Fit is crucial: too loose and cold water flushes through; too tight and you can't paddle. The other big choice is thickness, which depends on water temperature, and entry style (back zip or chest zip). Surfers, paddlers, divers and swimmers all use wetsuits, though dive suits and triathlon suits are specialized.

How to Choose
- Fit: snug with no gaps; try the brand's size chart.
- Entry: back zip for ease; chest zip for warmth and flex.
- Seams: glued and blind-stitched or taped seams keep more water out than flatlock.
- Use: surfing suits flex in the shoulders; dive suits differ.

Frequently Asked Questions
What thickness wetsuit do I need?
It depends on water temperature. Roughly: warm water calls for a shorty or 2mm, cool water a 3/2, and cold water a 4/3 or 5/4 with boots, gloves and hood. Check brand charts.
What does 3/2 mean?
3 mm neoprene on the torso for warmth and 2 mm on the arms and legs for flexibility.
Chest zip or back zip?
Back zips are easier to get on and off. Chest zips usually seal better and flex more.
How should a wetsuit fit?
Snug everywhere, with no large gaps or air pockets, but you should still be able to raise your arms and breathe comfortably.
How do I care for a wetsuit?
Rinse in fresh water after each use, dry it inside out in the shade and don't store it folded for long.
