Laugh in the face of long miles and cold, wet nights when you're carrying the Marmot Cloudbreak 20 Sleeping Bag in your backpack. Two types of ultralight synthetic insulation give this sleeping bag a 20 degree temperature rating, a weight of just under three pounds, and the unique ability to retain warmth even when wet. Marmot's engineers used 'anchors' of Thermal R Micro to add insulation at your feet and core, while the basic Thermal R insulation takes care of everything else from your ankles to waist and from your shoulders to head. Other features include a shell with a water resistant coating, a hood designed for maximum heat retention and comfort, and unique baffles that utilize a shingle like structure to eliminate cold spots inside. Aside from the more recreational style Maverick or Rockaway sleeping bags, the Cloudbreak is the only 20 degree sleeping bag in Marmot's entire lineup the standard temperature degree ratings are 0, 15, and 30. This sleeping bag is ideal for backpackers who want a lightweight, three season synthetic sleeping bag solution or wet weather campers who need something cooler than a 15 degree sleeping bag and who would rather not make the leap all the way up to 30 degrees.
