SEAC DryTek Man 4 mm Neoprene Drysuit

The SEAC DryTek Man is our neoprene drysuit option: a men's suit made from 4 mm HD compressed neoprene, with integrated boots and reinforced wear areas. It offers the built-in insulation and robust feel that many divers value in neoprene, at a more accessible entry price.

Why we've selected it

We generally recommend trilaminate drysuits for their versatility and the freedom to adjust your layering across the seasons. Neoprene still has a place: if you prefer a suit that contributes its own insulation, with a substantial construction for regular diving, DryTek provides an alternative in the Oceanauts range.

Fit and sizing

Available in S, M, L, L2P, XL, XL2P, XXL, XXL2P, XXXL, XXXL2P and XXXXL. Contact Oceanauts before ordering so we can help check body fit, boot sizing and room for your intended undergarments. A drysuit should allow comfortable movement in your full diving layers.
