When room and lots of it is the issue, then get into something with 67″ of shoulder girth and 48″ wide inches at the foot. For sheer comfort our Ponderosa is the bag for big folks and claustrophobes alike. This large volume semi-rectangular bag has 7″ of loft from 27 ounces of 850 fill power down. And in spite of its size weighs in at only 2 lbs. 9 oz. Depending on your size you can enjoy this bag down to 15°. The Ponderosa will zip to our mummy bags, and if the nights are really mild, unzip the bag around the foot and mate it to our Summer Coupler. Now you can roll across a couple of time zones without leaving your bag! This bag is also available in 7′ length.
