BIG AGNES THUNDERHEAD SL 30 LONG LEFT SLEEPING BAG

Do you hear that? It's the silence in your tent when your bag doesn't have a zipper. No more zzzzzzip sounds when you want to get in and out of your bag quietly. 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.
