This pfd is perfect for my application (saltwater kayak fishing). The four large pockets are great for holding things that you need on hand while fishing (small tackle box, granola bars, knife, vhf radio, etc.), as well as emergency equipment (basic first aid kit and flares). Given the limited storage on my SOT kayak, this close-at-hand storage is really useful on the water. And, I like the ability to keep my safety equipment on me, given that if I were in an emergency situation, my yak might be unreachable. The highback does not interfere with my seat at all either, while the mesh shoulder straps breath quite well. Very well designed product--would definitely recommend.
