The Kokatat Ronin Personal Flotation Device includes full-length spinal protection and padded shoulders to help you make it through a nasty swim in a rocky river. Despite the added protection, the Ronin Personal Flotation Device still has a low-profile cut that works well for anything from rafting to creek boating to sea kayaking. Kokatat's internal grip panel and offset front-entry design create a snug fit that won't ride up when you're in the water.
