Fourth Element Women’s Arctic One Piece Details

The Fourth Element Women’s Arctic One Piece delivers exceptional thermal protection while maintaining mobility and low bulk — a balance often hard to find in undersuits. The dual-layer design traps warmth close to the body while wicking away moisture, forming a stable microclimate even under demanding conditions. This can provide enough thermal insulation to keep you comfortable even if your drysuit seals fail — a testament to its robust performance. 

The snug but flexible cut ensures a good fit under lighter neoprene, membrane, or trilaminate drysuits. The low-profile construction avoids excess bulk, making it easier to don and doff, while the thoughtful touches — like thumb loops, foot stirrups, and a low front zipper — streamline gear-up on boats or during shore dives. Many dive centres and military dive teams worldwide trust the Arctic undersuit for daily diving, endorsing its reliability and longevity.
