Made with the latest Gore-Tex Pro material that makes a lighter, more rugged and durable dry top. The OM is Kokatat's most advanced dry top to date. It features a new pattern for improved fit and mobility as well as latex gaskets with neoprene punch through cuffs on the neck and wrists and a self-draining pocket on the left shoulder. The OM has a lightweight Gore-Tex Pro inner skirt as part of its adjustable double tunnel waist featuring Ariaprene, a sustainable alternative to neoprene, and provides an infinitely adjustable perfect fit.
