Sierra Designs Big Dog 20 Degree Sleeping Bag

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.
