650-fill DownTek insulation absorbs 30% less water and dries 60% faster than untreated down, and retains significantly more loft than untreated down after exposure to moisture. Insotect Flow construction keeps the insulation next to your body for more efficient heat distribution, and a semirectangular shape provides a comfy cozy sleep experience. Polyester mini-ripstop microfiber shell fabric is soft and sports a durable water repellent (DWR) finish to fend off light rain and stains. Sculpted contour allows the bag to drape around you, increasing insulation performance. Free Range Hood design gives you the freedom to lift your head while snuggled in the hood.
Design improves connection between integrated pad sleeve and bag, providing a roomier sleeping space without adding bulk. Low-profile cordlock lets you un-cinch the hood with just one hand. Tapered, vaulted footbox creates wiggle room for your feet without creating large cold air pockets. Stretch fabric panel beneath hood creates a designated pillow pocket. (178cm) YKK #8 zipper with zipper garage. Mate together left and right zip bags. No-draft collar; no-draft wedge; no-draft zipper. Interior fabric loops for sleeping bag liners; exterior loops for hang drying or storage. Includes a mesh storage sack and nylon stuff sack.
