Our polyolefin Hot Skins are perfect for layering under a neoprene wetsuit, they are resistant to chlorine, anti-microbial and will not fade in sunlight. In other words, they’ll keep you warm, comfortable and looking great and won’t begin to smell like an old pair of socks after a few dives. Henderson polyolefin products are an excellent choice for the active diver who likes the comfort of lycra® but requires commercial quality.
