Sierra Designs Men's Hibernator:
What's the big deal about Sierra Design's Flex™ bags? Before creating the Flex™ series, Sierra Design considered some important sleeping facts, stuff like only 24% of us actually sleep on our backs and that we change our sleeping position at least 40 times per night. With this data in mind, they created a revolutionary Flex™ design that allows you to move around without sacrificing thermal performance. Try that with an ordinary mummy bag and you'll find that: a. you can't move or b. you're out in the cold. All Flex™ sleeping bags have a patented Nightcap™ hood with two adjustments that ensure warmth and coverage in any position. The Hibernator also features External Pad Locks™ to keep your mattress pad in place as you move. Give a Flex™ bag a try and see how much better you sleep through the night.
