Thermal Underfleece Suits for Dinghy Sailing

Thermal one-piece underfleece suits are the ultimate base layer worn under drysuits: they deliver constant warmth during long winter passages and training in the coldest waters. A single garment covers torso and legs, eliminating draughts and cold spots.

Made from breathable technical fleece, they retain body heat while keeping the skin dry through fast moisture wicking. A long zip makes dressing easy, while elasticated cuffs and ankles seal the warmth inside the drysuit.

They are essential for winter sailing on offshore dinghies, skiffs and for foiling, where exposure to cold is prolonged. To choose, select the size based on your drysuit. Leading brands: Zhik, Vaikobi, GUL and Musto.
