If you can only have one PFD, make it the Liquid FOrce Classic Hinge CGA Vest. It provides the safety you need, with PVX and PVA Foam Hybrid panels and fully-certified US Coast Guard Approval so it even counts as a PFD while you're on the boat. But it does it with a design that's committed to movement, from the oversized arm holes to the Five Flex Panel Design. Taken together that gives you essentially unrestricted movement, improving performance and comfort in or out of the water.
