A high performance, lightweight one-piece union suit designed to wear under a dry suit or any time you need to be prepared for a variety of conditions.

Crafted from 4-way stretch Polartec® Power Grid™ fleece, it provides temperature regulation and moisture wicking—keeping you warm even if it gets wet. We built it with a super-stretch neoprene neck entry to eliminate zippers under your gear. Complete with a front fly and a form-fitting cut, it’s the base layer you want.
