The Code Zero X Thermotop represents the pinnacle of GUL's sailing wetsuit innovation, engineered to deliver exceptional warmth, flexibility and durability when conditions are at their toughest. Designed for sailors who refuse to let cold weather limit performance, it combines premium sustainable materials with advanced thermal technology to keep you comfortable on the water for longer.

Constructed from 3mm Rhombus|Flex super-stretch NAECO FSC® & PEFC® certified natural rubber foam, the Code Zero X Thermotop offers an outstanding balance of thermal protection and unrestricted movement. The highly flexible outer fabric allows complete freedom of movement for sailing, hiking and active manoeuvres, while maintaining the insulation required for cold-weather performance.

Inside, the Thermospan thermal lining is designed to retain body heat and regulate temperature, providing lasting warmth and comfort during extended sessions in challenging conditions. Blindstitched seam construction combined with G-Tape internal taping helps minimise water ingress, improve durability and maximise heat retention.

Additional performance features include a Silicone Octogrip waistband hem to help keep the top securely in place, an Ultra Flex neck seal for superior comfort, embossed elbow articulation for unrestricted movement, and RevOfit 3D Pattern Technology for an ergonomic performance fit. Finished with True Thickness Foam and UV Shield 50+ UVA & UVB protection, the Code Zero X Thermotop is built to perform beyond what's necessary.
