The new generation Performance Wear is designed for active water athletes who need warmth, flexibility and performance without restriction. Built around intelligent panel placement, this updated design combines proven Chillproof 3-layer core protection with advanced Thermal Flex through the arms, shoulders and gussets. The result is a warmer, more flexible and more responsive performance top made for high-output water sports. The Chillproof core provides windproof, breathable insulation across the front body, helping keep you warm in wind, spray and changing conditions. Added Chillproof coverage across the upper back boosts warmth where you need it most, while the chest zip makes the top easier to get on and off. The major upgrade is the introduction of Thermal Flex in the arms and movement zones. This advanced fabric delivers impressive warmth without bulk, high-density 4-way stretch for unrestricted shoulder rotation, and Hydro-Lock DWR technology to help reduce water absorption and surface drag. Embedded far infrared technology supports thermoregulation, circulation and muscle recovery during training, competition and long sessions in the water. UPF50+ sun protection, a higher neck profile and zero-chafe soft stitch panels provide extra comfort and coverage for extended use. Warm through the core. Flexible through the arms. Built for surfing, ocean swimming, surf ski, SUP, sailing, foiling, multisport and all action water sports.
