Sharkskin Chillproof Long Sleeve Step-In (Women's)

The Sharkskin Chillproof Long Sleeve Step-In is a women's thermal top with an integrated step-in base, so it stays in place instead of creeping up your back when you move. Divers and snorkelers can wear it alone in warmer water or pull a wetsuit on over it when the water and wind turn cool.

Wearing the Step-In for Diving and Snorkeling

Sharkskin says its three-layer Chillproof fabric has the thermal properties of a 2.5 to 3mm neoprene wetsuit. Under a wetsuit it adds warmth and wind protection, and on its own it works as a complete thermal layer.

• The membrane is 100% windproof yet breathable (10K+), which helps you stay warm on a breezy boat without overheating.
• Hollow fiber fleece sits next to the skin and wicks moisture.
• Thumb tabs inside the sleeves keep the cuffs from bunching while you pull a wetsuit over the top.
• The fabric is neutrally buoyant and rated UPF50+.

Fit and Sizing

This is a women's cut, sold in black in US sizes 0 through 16. The four-way stretch fabric moves with you and is easy to get on and off, and the step-in base keeps the hem from riding up while you kick or climb a boat ladder.
