The North Face One Bag Sleeping Bag Regular +4/-7/-15C

One bag to rule them all—The North Face One Bag Sleeping Bag redefines versatility with its revolutionary 3-in-1 modular design that adapts to temperatures from balmy +4°C to frigid -15°C. Instead of stuffing multiple sleeping bags into your pack for changing conditions, simply configure the layers to match your environment: use the lightweight synthetic HEATSEEKER™ top layer for warm summer nights, switch to the 700-fill recycled down mid-layer for crisp autumn evenings, or combine both for winter expeditions. The anti-compression synthetic layer along the back eliminates cold spots where your body typically flattens insulation, ensuring consistent warmth throughout the night regardless of your sleeping position.

Perfect for multi-season backpackers and altitude-hopping adventurers, this ingenious system continues to impress beyond bedtime—the down layer doubles as a standalone quilt for fireside lounging, while the included compression sack transforms into a camp pillow. Crafted with recycled materials throughout, from the 20D ripstop nylon shell to the eco-conscious insulation, the One Bag delivers exceptional environmental credentials without compromising performance. Whether you're tackling changing mountain weather or planning a year-round camping calendar with a single piece of gear, this sleeping bag's three-temperature versatility delivers the ultimate combination of packability, adaptability, and all-night comfort in every climate.
