The Thunderhead SL bag features cozy cocoon style construction with an easy, weight-saving clip and loop system in place of the traditional zipper. With an integrated half pad sleeve on the bottom, a vaulted foot box with ample wiggle room, and vertically structured side walls that trap heat closer to your body, this 650 fill power DownTek™ bag is the perfect all-in-one sleeping bag for backpacking or any backcountry outing.

While down bags generally cost more and require more care to keep dry in humid conditions, the soft feel of down is unsurpassed and extremely popular. This Big Agnes sleeping bag features DownTek water repellent down insulation which repels water while maintaining it's loft and insulation value.
