K01 - Drysuit Undersuit

K01 - Drysuit Undersuit

Premium warmth and comfort starts with what’s underneath.

The K01 Undersuit is built for divers who spend long hours in a drysuit and want warmth without bulk, restriction, or uncomfortable seams. Designed with K01’s seamless knitted construction and stretch-fit fabric technology, it moves naturally with your body while helping maintain thermal comfort during demanding dives.

Unlike traditional bulky undergarments that bunch, bind, or restrict mobility, the K01 Undersuit wraps closely to the body with a soft, flexible fit that layers comfortably beneath a drysuit. The ergonomic construction reduces pressure points and helps improve comfort during long days of diving, travel, training, cave diving, technical diving, or cold-water exploration.

Thoughtful diver-focused details include integrated P-valve routing access, reinforced knee zones, dual side pockets, a chest zip pocket, and a two-way zipper for convenience.

Whether you’re spending an hour in cold water or gearing up for long decompression dives, the K01 Undersuit was designed to help you stay warmer, more comfortable, and focused on the dive.
