Marmot Mad River Sleeping Bag

The 40° rating indicates the temperature at which the average sleeper will remain comfortable and warm. Because this is a lightweight bag designed for warmer conditions, it is best suited for late spring, summer, and early fall backpacking trips.

Unlike traditional DWR coatings that are applied to the fabric, ExpeDry is a chemical-free treatment applied directly to the down feathers. It helps the down dry faster and maintain its loft in humid conditions without the use of harsh chemicals.

Yes, the long version of this bag is specifically designed to accommodate sleepers up to 6'6". The anatomically designed footbox also provides extra room, so you shouldn't feel cramped at the bottom of the bag.

The full-length left zipper is for easy entry and exit, while the shorter right-side zipper allows you to fold down the top of the bag like a comforter. This dual-zipper system gives you much more control over ventilation and sleeping positions on warmer nights.

Yes, this bag uses RDS-certified (Responsible Down Standard) goose down. This certification ensures that the down comes from ducks and geese that have been treated humanely throughout their lives.

The draft collar is an insulated tube that sits around your neck and shoulders. It acts as a seal to prevent warm air from escaping the bag when you move around, which is essential for staying warm on cooler nights.
