Why waste precious space in your pack with unnecessary materials. The Helium 600 +14 Down Sleeping Bag from Mountain Equipment is highly compressible and will leave you with plenty of room to spare. Ultralight fabrics and box baffles filled with 725 fill down significantly reduce the overall weight of the bag while giving you top of the line comfort. The anatomically shaped foot box with a 4 baffle end allows your feet to rest comfortably without compressing the down so you stay warmer. A shaped hood and neck collar ensure that you retain as much heat as possible so you get a good night's sleep.
