When you need to extend the range of your sleeping bag system, play it safe and carry our 14 ounce EverLite. This mummy-cut, box stitched, sewn-thru sleeping bag is made for both efficiency and versatility.   There is no foot box and it features a very lightweight and compact YKK size #3 coil zipper.   This design allows the bag to be opened up completely to use like a tapered blanket for car camping or threaded over a hammock and zipped up to provide insulation all around your body.
