This is Extrasport's premier front-zip PFD. Like the Vapor, the 500 x 500-denier Cordura shell resists abrasion and adds strength to the shoulder straps. The short-waisted design stays out of your way when you're sitting. A segmented back panel wraps comfortably around you, and is cut lower at the top for increased shoulder and arm mobility. Design Flotation: 16 lbs.
