NRS designed the Odyssey Personal Flotation Device with full mobility in mind for sea kayakers and touring. It's a type III PFD that uses NRS's Cool Flow System for advanced ventilation as well as mobility. There are six adjustable straps to customize the fit, and a zippered front entry secures the fit. Two of the four front pockets are dual-entry and sized for VHF radios, and 3M paneling along the upper back adds visibility in low light.
