Learn More rntttt Fins are difficult to carry, especially if you are operating a PWC or are ready to toss a throw bag. Designed with the help of river rescue professionals and lifeguards, our SRT Accessory Belt holds a fin on each hip with buckles that allow quick release of the fins even when in the water. The back of the belt has a place to attach a river knife and a few loops for clipping carabiners. The dive-type waist buckle can be released even under load. (Accessories not included.) One size fits most rescuers.
