Chillproof

Chillproof by Sharkskin is the smart alternative to a 3mm wetsuit—engineered to keep you cool when it’s hot and warm when it’s cold, in, on, or under the water.

Built from a revolutionary trilaminate, Chillproof features:
• Outer layer: 4-way stretch with DWR for durability and water resistance
• Middle layer: Windproof, breathable membrane to stop windchill and prevent overheating
• Inner layer: Hollow-fibre fleece that insulates when wet and wicks moisture on the surface

How it works:
• In the water: Fleece traps water, your body heats it, and flushing is minimized—like a wetsuit, without the bulk
• On the surface: Blocks wind, repels water, holds warm air, and breathes to release excess heat
