The Mountain Equipment Women's Helium 600 14 Down Sleeping Bag is light on weight and heavy on warmth for frigid backpacking trips. The Helium truly lives up to its name, with lightweight 725-fill down insulation and an ultralight Helium shell that compresses for compact storage. Slanted baffle construction assists with compression and keeps the down in place to prevent cold spots. An alpine mummy fit offers a little more room for extra comfort. Inside the Helium, you get a Supersoft 20 lining to keep you cozy throughout the night. Like the bag, the DC5 hood's baffled construction keeps the down in place for a cushy head-space. Mountain Equipment also added a roomy Trapezium 4 foot box, a draft-blocking Solus collar, and draft tubes down the side zipper.
The Helium 600 women's down sleeping bag by Mountain Equipment showcases 50 years of experience in making down bags. They understand the needs of climbers and backpackers and it shows.
Why waste precious space in your pack with unnecessary materials. The Helium 600 +14 Women's 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.
