Big Agnes Pin Ears SL Sleeping Bag 20 Degree Down

The Big Agnes Pin Ears SL 20 Degree Sleeping Bag is optimized for ultra light backpackers looking to ditch weight without sacrificing warmth. It's rated to 20F, giving you versatility for three season outings and milder winter conditions. 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. An oversized anti draft collar wraps around the entire body to create a 3D barrier against cold spots. It's stuffed with DownTek 650 fill insulation, which maximizes lofting power while improving compression for compact carrying in your pack. To handle wet conditions, the down insulation features a hydrophobic treatment that repels outside moisture from compromising its heat trapping loft. For even greater warmth, vertically structured sidewalls with diagonal baffles wrap around your body, much like a cozy cocoon. Another nifty design feature is the half pad sleeve, which keeps you secure while allowing your feet to freely move.
