Boys will appreciate our cold-weather workhorse, the Big Dog. Rated to 20 degrees and filled with HeatSync insulation, the Big Dog packs warmth and comfort into a cool-looking bag. An attached stuff sack won't get lost, and a Sleep E-Z Pillow (included) stows in its own pillow pocket. The ergonomic hood and draft tube retain heat and a tricot-lined foot box provides additional insulation for feet. less

Sierra Designs couldn't have given the Men's Wicked Light 45 Degree Down Sleeping Bag a more appropriate name--it barely tips the scales with a 22oz weight. This isn't some feature-strippe­d bag. Sierra Designs added a full-length zipper for ease of use and draw cord around the collar to keep out the cold air. The Wicked Light Sleeping Bag's lofty 800-fill down insulation provides incredible warmth for its weight, so you don't have to choose between a warm night and a light pack. less

We've adapted the Flex construction to Ultralight bags, using expandable-baff­le Flex from the shoulder to the knees for comfort, without adding significant weight. less
