A high-end option for truly challenging conditions in extreme cold, the Mountain Hardwear Phantom GORE-TEX 0 Degree sleeping bag encases 850-fill down insulation in premium GORE-TEX WINDSTOPPER fabric to deliver lightweight, compressible, water-and-wind-resistant performance for alpine climbing and 4-season backpacking.
The bag is insulated with premium 850-fill, RDS-certified goose down insulation. Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel and, despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. Down is, however, susceptible to a performance drop-off if it becomes damp or wet, but the bag's breathable GORE-TEX WINDSTOPPER shell fabric bolsters protection by adding both water-resistance and wind-resistance.
An expedition-mummy shape balances thermal efficiency, internal space, and weight. Horizontal baffles and vertical side baffles help to keep insulation evenly distributed, so you enjoy consistent warmth. An insulated hood with an oversized down-filled face gasket ensures close-fitting warmth around your face, neck, and head. Other features include an oversized, insulated draft tube behind the two-way zipper, glow in the dark zipper pulls, a contoured footbox, an included nylon compression sack, and a mesh storage sack.
The Mountain Hardwear Phantom GORE-TEX 0 Degree sleeping is available in Regular (6' 0") and Long (6' 6") lengths.
