The Men's Kokatat Radius is an expedition-grade drysuit with the new SwitchZip Technology system. This gives you the choice of dry top, dry pants or a fully waterproof kayaker's drysuit. The flexible TIZIPA(R) fully-separating zipper at the waist makes suit entry a snap. Pull on the upper just as you would a dry top, then don the pants, fasten the zipper and you have a drysuit. Or, you can just mate the top with your sprayskirt for a fully functional dry top. When conditions warrant you can also wear just the pants. The zipper sits below the dual adjustable overskirt. In your boat this puts the zipper between the backband and seat so it doesn't interfere with your life jacket or kayak rigging. There's no need for a separate relief zippers, SwitchZip covers all nature-call situations. Soft, supple GORE-TEXA(R) Evolution 3.21, with 330 CorduraA(R) Gore-Tex Pro on shoulder, sleeve and leg high-wear areas. Attached socks are made with GORE-TEX fabric, fully seam taped for durability and waterproofness. Stowable and removable GORE-TEX PacliteA(R) hood blocks the elements and increases comfort. Tough latex neck and wrist gaskets with neoprene punch-through protective covers keep water from your insulating layers. Two zippered sleeve pockets for easy small gear item access.
