The Drifter is a comfy, low profile PFD with articulated wrap around foam panels. It is cut away at the arms for free range of movement while paddling. The cross-chest cinch harness system keeps the PFD from riding up, and the fleece lined handwarmer pockets keep your paws warm. It's also got two large zippered pockets, and lash tabs on the chest and back shoulder. This is a good PFD for sailing as well as paddling, as the shoulder strap buckles tuck out of the way into a sleeve so they don't catch on anything.
Graded sizing means the smaller sizes have smaller and less thick foam bodies rather than simply shorter straps. That way regardless of size you'll get a PFD that fits, which is safer, more comfortable, and lets you move freely. Canadian approved.
