Gul Code Zero X Naeco 3mm GBS Blindstitched Long John Wetsuit

The GUL Code Zero X Long John is a premium performance sailing wetsuit designed for dinghy sailors and watersports enthusiasts who demand exceptional warmth, flexibility and durability. Part of GUL's advanced Code Zero X collection, this technical wetsuit Long John combines sustainable natural rubber foam with innovative thermal technology and strategically reinforced panels. Ideal for competitive dinghy sailing, foiling, training and racing, it provides the freedom of movement and protection required for demanding conditions on the water.

Constructed using NAECO FSC® & PEFC® certified natural rubber foam, the Code Zero X Long John combines insulation with a flexible, performance-focused fit. Its Rhombus|Flex upper panels provide exceptional stretch around the torso, allowing unrestricted movement when trimming sails, hiking or manoeuvring around the boat. Lightweight FX:Lite lower panels complement this flexibility, helping maintain comfortable movement through the hips and legs during active sailing.

For warmth in colder conditions, the Long John incorporates a Thermospan Thermal Lining and targeted Graphene X Boltdry+ Kidney Panel. These advanced materials are designed to help retain body heat and provide thermal comfort around the core and lower back. Blindstitched seam construction with G-Tape internal seam taping helps minimise water ingress while reinforcing the seams for improved durability and comfort during prolonged sessions on the water.

Durability is enhanced through a rugged Flextex reinforced seat panel and Powertex4 abrasion-resistant knee pads, providing additional protection in areas exposed to repeated contact with dinghy decks and fittings. The innovative S-Shield Hex Flex Shin Protection offers targeted protection to the lower legs, while embossed knee articulation allows comfortable bending and movement. A discreet low-profile side leg pocket provides convenient storage without adding unnecessary bulk.

Practical sailing features include GUL's Flow Lower Leg Drainage System, designed to help release trapped water, and S-Seal Ankle Seals for a secure fit around the lower legs. RevOfit 3D Pattern Technology provides an ergonomic shape that follows the body's natural movements, while the P-Eazy Fly Relief System adds convenience during extended sailing sessions. Finished with True Thickness Foam and UV Shield 50+ UVA & UVB protection, the GUL Code Zero X Long John delivers a technical combination of warmth, flexibility, protection and durability for serious sailors.
