Exped’s roomy Comfort 400 lived up to its name with a generous cut that allowed campers to move and reposition during the night without feeling constricted. The 840-fill down lofts up nicely to insulate well even when temperatures dip into the upper 20s. The addition of the full-length zipper makes the bag a useful summer bed—fully opened it can be a quilt to cover two friendly campers, or as an airy throw over just one sleeper.

Compressibility
That premium 840-fill goose down compresses into a grapefruit-sized bundle that tucks out of the same in the smallest weekend packs. The high compressibility is a notable plus for this bag.

Warmth-to-weight and comfort
The Comfort 400 boasts remarkable loft for a 32º bag, and though the weight is greater than some of the other bags in this class, most of that added weight comes from its comfortable cut and the durable full-length zipper. Considering that, the warmth to ratio is at or near the top of this class (among generously cut bags).

The 46-denier polyester lining feels like a slick, soft sheet against the skin, making for one of the coziest backcountry beds we’ve experienced.

The looser cut is going be appreciated by stouter and more broad-shouldered sleepers, although thinner folks may loose some heating efficiency and perceive the bag to sleep “colder” than bigger campers.

Durability
The 35-denier nylon shell bumps the weight up compared to some of the competitors, but it also provides a bit of protection from snags and tears. Indeed, this is the only bag in this class that came through the extensive testing (in 3 states) and our standard two wash cycles looking like new.
