Sharkskin CHILLPROOF Long Sleeve Mens Black/Silver

Chillproof by Sharkskin is a revolutionary high-tech trilaminate (3-layer) material with the same warmth as a 3mm wetsuit, keeping you cool when it's hot and warm when you're cold. Chillproof is designed for in, on, and under the water. Sharkskin Chillproof Materials

1. The outer layer is a tough and durable, high-quality 4-way stretch material with a water-repellent finish.

2. The second middle layer is a 10,000+ technical membrane that both stops wind chill and breathes to prevent overheating.

3. The skin-friendly inner layer is a unique hollow fiber fleece that retains water when submerged and wicks away moisture when lying on the surface to dry quickly and provide a comfortable feel.

Sharkskin is truly the smart skin everyone's talking about. Sharkskin Chillproof has exceptional properties that keep you warm and comfortable whether fully submerged or above water—wet or dry.

In water

A traditional wetsuit consists of a rubber-like material filled with bladders. A small amount of water is trapped inside the suit, and the bladders insulate you to prevent heat loss. The thicker the suit, the more bubbles and the more insulation it provides. When used for scuba diving or freediving, wetsuits compress at depth, reducing insulation and buoyancy.

Chillproof works on a different system. When submerged, the hollow-fiber fleece is designed to absorb and trap a significant amount of water, and the membrane retains the water. Your body heats this trapped water, creating a barrier against the cold water outside the garment equivalent to a 3mm wetsuit. It's neutrally buoyant, meaning less weight can be carried on your weight belt, won't compress at depth, thus maintaining its insulating properties, and is much less cumbersome and restrictive than a wetsuit for activities above and below water.

Above water

On the surface, Chillproof provides a windproof and water-repellent barrier against the elements. The hollow-fiber fleece traps and retains air, which your body then heats to keep you warm with minimal bulk. Any moisture is quickly wicked away, and excess heat or water vapor permeates through the semi-permeable, one-way membrane to limit overheating.

Even if Chillproof gets wet above water, your body heat is trapped in the hollow fiber fleece layer to keep you warm. Your body heat helps evaporate the water retained in the garment through the one-way membrane. Air replaces the evaporated water in the fleece, which in turn is warmed by your body to form an insulating layer and continue to keep you warm.

Wet and dry

In many water sports, you're dry one minute and wet in the water the next, or vice versa. Sharkskin Chillproof works equally well wet or dry and can be used for a variety of water activities where you're both above and below water during the same session. The traditional wetsuit has many limitations both in and out of the water, but these limitations are further compounded as you move around in and out of the water. Wetsuits aren't windchill resistant, and so your body heat can drop quickly when you get out of the water in a wet wetsuit. Wetsuits are also not as flexible as Sharkskin, limiting activities like kayaking, SUP paddling, etc.
