The Kokatat Hydrus Swift Entry Drysuit with relief zipper and socks is an affordable way to stay dry all day. The Hydrus super tough nylon woven outer layer provides long lasting abrasion resistance and features a DWR coating to repel water. The mid-layer utilizes a polyurethane micro-porous coating, allowing water vapor to transfer from the inner layer to the outer. The soft, knit-polyester inner layer is designed to help wick moisture, moving it from the inside out. The result is an exceptionally waterproof, breathable alternative that stays dry and comfortable. Hydrus 3.0 (3 layer) fabric. Great for rafters, canoeists and SUPers. Kayakers will want to go with the Kokatat Hydrus Meridian Drysuit.
