Mustang Survival Catalyst Flotation jacket is much more comfortable than the old style floater coats. It utilizes the M-TECH comfort system to keep you dry and float you when you need it. This revolutionary system uses three layers to add to your comfort. The first is a wicking lining that aids in breathability, the second is the segemented foam that moves and flexes as you do, and the third is a waterproof, breathable, tri-laminate outer shell that keeps rain and spray in the ocean where they belong. This jacket also features a integrated hood.
