Marmot Angel Fire Sleeping Bag

The 25°F rating indicates the lower limit where the average user should remain comfortable. For most three-season camping, this provides a solid buffer, but if you are a cold sleeper, you may want to pair it with a high-R-value sleeping pad or a liner when temperatures drop near freezing.

The Down Defender treatment helps the down insulation resist moisture and retain its loft longer than untreated down. While it significantly improves performance in damp environments, it is still a down bag, so you should avoid submerging it or exposing it to heavy, direct rain.

The secondary zipper allows you to fold down the top section of the bag, similar to a comforter. This is incredibly useful for temperature regulation on warmer nights or for sitting up inside the bag to read or cook without having to fully exit.

Yes, at 2.625 lbs and a compressed volume of 7.6 liters, it strikes a good balance between warmth and packability. It is well-suited for multi-day backcountry trips where weight and space in your pack are considerations.

The wrap-around footbox is shaped to follow the natural position of your feet while you sleep. This design prevents the insulation from being compressed by your toes, which keeps the down lofted and your feet warmer throughout the night.

The internal heater pockets are designed to hold hand warmers or small items you want to keep from freezing overnight. Placing a heat source here can help warm your core or extremities more effectively than keeping them loose in the bag.
