The Kokatat Men's PolartecA(R) Power DryA(R) liner provides warmth and moisture wicking without excess bulk. The union suit design works great under a drysuit, and the fabric comes from 92% recycled material. Four-way-stretch Polartec Power Dry material keeps you warm and transports moisture away from your skin so you can paddle in comfort all day. The soft velour interior feels great against your skin. The paddling-specific design and durable jersey facing enable smooth layering with outer layers such as drysuits and dry tops. A front entry zipper makes this union suit easy to put on and take off, and the zip flap and chin guard keep the zipper from rubbing. The convenient men's relief zipper lets you answer nature's call without removing the liner. Articulated for comfort and unrestricted movement. Flat-stitched seams for rugged durability and next-to-skin comfort.
