DETAILED DESCRIPTION
Warmth and Comfort at its Core
The Hot Stuff 3.0 lining provides effective insulation by trapping air within its large loops, while remaining very stretchy. It's complemented by Silk Stuff 2.0, which offers a soft, smooth feel against your skin on the legs and sleeves. Together, these linings deliver lasting warmth and comfort for your cold-water sessions.
Optimised Mobility for Every Discipline
The seamless Sweep_Cut shoulders and minimal panel layout deliver an excellent range of motion. When paddling for a wave or maneuvering your kite or wing, this wetsuit moves with you without restriction.
Built to Last
Glued Blind Stitch seams, combined with strategic Maki_Tape 2.0 reinforcements, effectively seal out water and protect high-stress areas. The result is a durable wetsuit that maintains its performance season after season.
Practical Rider-Focused Features
Features like the Water Defender system prevent the leg cuffs from riding up, while drain holes quickly flush out any water that gets inside. A handy key pocket and detachable leg straps add extra convenience to your sessions.
