Sharkskin Chillproof Back Zip Suit (Men's)

The Sharkskin Chillproof Back Zip Suit is a one-piece full suit that men can wear in place of a wetsuit on warm-water dives and snorkels, or underneath a wetsuit when the water turns cold. It gives you full body coverage, so you also get protection from the sun and from marine stingers on reef dives. Because it is less buoyant than neoprene, you need less lead on your weight belt, which makes for a more comfortable dive.

How Chillproof Works in a Full Suit

Chillproof is a three-layer composite that Sharkskin rates at the thermal equivalent of a 2.5 to 3mm neoprene wetsuit.

• Nylon/Spandex outer layer that stands up to abrasion
• 100% windproof membrane, breathable to 10K+, that stops windchill on the boat without trapping heat
• Hollow fiber fleece against the skin that wicks moisture
• Neoprene rubber collar that forms a flexible neck seal
• UPF50+ sun protection and a DWR finish that sheds water

Men's Fit and Sizing

The men's cut runs from SML through 5XL. MED through XLG also come in -S and -T versions, the short and tall options. 4-way stretch lets the suit move with you and makes it easy to step into. Colors are Black or Black / Blue.
