You got to flex it if you want to sex it, baby! The beach is (flex bicep while pointing with thumb) thataway! Sierra Designs has been flexing it fro some time now with their sleeping bags. Their 3-season bags use an elastic tape and their ultralight bags use an elastci thread, as the the Flex down jacket. Kudos up front: the Flex uses 100% recycled polyester fibers in teh shell fabric.
