Big Agnes Thunderhead SL 30 Sleeping Bag 650 DownTek

Maximize your mileage without sacrificing warmth on chilly evenings with the Big Agnes Thunderhead SL 30 Degree Down Sleeping Bag. This ultra-light bag allows you to move quickly across large swaths of wilderness without excess weight holding you back. It's rated to 30F, giving you versatility for three-season backpacking trips. The bag's minimalist design saves weight by replacing the zipper with a hook-and-clip system that's both intuitive and silent to operate. Stuffed with 650-fill DownTek insulation, the Thunderhead SL maintains toasty warmth in freezing overnight temperatures. For wet conditions where traditional down would normally lose its heat retention, DownTek employs a hydrophobic treatment that repels outside moisture from sapping your warmth. To maximize thermal efficiency, vertically structured sidewalls use diagonal baffles to wrap your body, much like a cozy cocoon. This design helps you snooze soundly while your camp partners are shivering inside their bags.
