Western Mountaineering Apache MF Sleeping Bag - 2-3 Season to -9°C

The Western Mountaineering Apache MF sleeping bag is a lightweight 2-3 season down bag that pushes into colder conditions. Rated to -9°C at around 900g, it covers shoulder-season trips, alpine bivouacs and unpredictable weather without adding unnecessary weight.

15cm (6") of loft from 850+ fill power goose down gives an excellent warmth-to-weight ratio, long-lasting loft and high compressibility. Continuous baffles let you shift down for colder nights or balance it in milder weather, and a full down-filled draft collar reduces heat loss when temperatures drop. The 20D MicroLite XP shell is breathable and water-resistant for mixed conditions, and the efficient mummy cut heats up quickly while keeping weight and bulk low. Choose the Apache MF when you want one bag for spring and autumn climbing, cool summer nights at altitude and fast and light missions.
