Sharkskin Long Sleeves are undergarments that are thin and comfy to wear but actually help you stay warmer by adding the same warmth as an additional 2.5-3mm wetsuit would provide.
Besides warmth the Sharkskin Long Sleeves provide you will UV protection, are neutrally buoyant (which is a major plus when scuba diving!), odour resistant, itch resistant and anti-microbial. They can even be washed in washing machines if you desire to do so and have thumb tabs to make it easier to put underneath an existing wetsuit!
Sharkskin Chillproof Long Sleeves are very cleverly designed with material that consists out of 3 layers. The inner layer is made of a special fleece material, that's good for sensitive skin and doesn't hold on to water. The middle layer provides protection of those nasty wind-chills and the outer layer is made of a special nylon/lycra layer that deters water and ensure a perfect fit. As Sharkskins don't hold on to a lot of water they dry fast as well.
