The North Face One Bag

The system uses two distinct layers that can be used separately or combined. You can use the synthetic top layer for milder 40°F nights, the down mid-layer for 20°F conditions, or zip them together for a deep-winter rating of 5°F.

Yes, the down layer is designed to function as a standalone campsite quilt. It is perfect for lounging around the fire or sleeping in warmer conditions when you do not need the full enclosure of the sleeping bag.

It is a clever dual-purpose design. Once you compress the bag, you can stuff the sack with extra clothing or soft gear to create a functional camp pillow, saving you space and weight in your pack.

The vaulted footbox is shaped to allow your feet to rest in a natural, upright position rather than being forced flat. This prevents the insulation from being compressed by your toes, which helps keep your feet warmer throughout the night.

The weight depends on the size you choose. The Regular size weighs 6 lbs 3.4 oz, while the Long version comes in at 6 lbs 9.26 oz.

The bag features a non-PFC DWR (durable water-repellent) finish on the shell. While it is excellent at shedding light moisture and condensation, it is not waterproof, so you should still use a tent or bivy in heavy rain.
