Seek Core 4/3 Front Zip 2025 Wetsuit

Performance & Feel

A change to natural rubber, sourced from oystershell powder, plant-based oil and eco-carbon black, means the suit is more flexible and lighter and you feel it. The suit moves more freely and sits lighter on the body than before. Hot_Stuff 3.0 across the torso is warmer and stretchier than the 2.0 it replaces, with larger loops in the recycled nylon lining trapping more air. Silk_Stuff 2.0 at the chest, shoulders and arms is made from recycled fabric and keeps entry and exit easy, with a smooth feel against bare skin.

The Sweep Cut seam-free shoulder design and Maki_Tape 2.0 reinforcement on the lower body seams and cuffs carry over from the 2023 suit unchanged, and the front zip cordlock still adjusts one-handed. Water Defender inserts at the ankle cuffs that stop the leg ends folding inward under pressure while this is a small detail, it keeps the suit fitting correctly and stops cold water getting a run up your ankles.
