The Mountainsmith Ptarmigan 35 Degree sleeping bag offers lightweight performance features at a budget-friendly price. A relaxed mummy cut and synthetic fill make the bag ideal for mild-weather camping or backpacking.
Weighing 2 pounds 14 ounces the Ptarmigan 35 Degree bag is insulated with compressible MountainLoft Hollowfibers synthetic fill. Though still not as compressible as natural down fill breathable and fast-drying MountainLoft unlike down fill is water-resistant and continues to provide warmth even when wet. This is particularly important if you'll be camping in wet weather or humid climates.
A differential cut and offset baffles optimizes loft and helps to eliminate cold spots keeping outside air from reaching the interior of the Ptarmigan 35 Degree. A draft tube behind the 3/4-length two-way locking zipper and a form fitting adjustable hood further enhance the thermal efficiency of the bag. The unique J-shape of the zipper allows you to vent the bag on warm evenings and even stick your feet entirely out of the bag. A contoured foot box enhances comfort and warmth.
The Mountainsmith Ptarmigan 35 Degree sleeping bag is available in a single length that fits to 6' 4". Each bag includes a Sil-Nylon stuff sack and a mesh storage sack.
