http://CampingGearTV.com - Sierra Designs keeps on pumpin' out the hits! We recently had the opportunity to try out their Pyro 15 sleeping bag, and it did not disappoint. This high-end 15 degree bag most notably comes with their Core Comfort body mapping technology, which places insulation in the areas it's most needed, thus reducing weight. The 600 fill down insulation bag weighs 2 lbs 13 oz and has a ton of great features. Check out the review and be sure to stop by http://www.sierradesigns.com/ for more!
