Bishop Pass Sleeping Bag: 0F Down

What Our Gearhead® Experts Are Saying:

"I recommend the Bishop Pass when you want a warmer down bag that still packs well for backpacking. The 650-fill down provides dependable insulation, and the Performance Plus mummy shape gives a little extra room without sacrificing warmth. It’s a great option for shoulder-season trips and cold nights when you still want a bag that compresses easily in your pack."

When frosty mornings and empty trails call us deeper into the backcountry, we rely on the Mountain Hardwear Bishop Pass Sleeping Bag to keep us warm through the night. Designed for colder conditions, this bag lets us stretch our camping season into late fall and early winter, whether we’re trekking through alpine forests or settling into a quiet campsite beneath crisp, star-filled skies.

Lofty 650-fill RDS-certified down insulation traps heat efficiently while remaining lightweight and packable for backpacking trips. The Performance Plus mummy shape provides a bit more room to move than traditional mummy bags, offering comfort without sacrificing thermal efficiency. A contoured footbox allows our toes to relax naturally, while the full-length draft tube and draft collar seal in warmth during colder nights.

Durable nylon fabrics with a water-resistant treatment help protect the insulation from damp conditions, keeping the down lofty and warm. The two-way zipper allows quick ventilation when temperatures rise, and a convenient internal stash pocket keeps small essentials like a headlamp or phone close at hand. Built for cold nights and extended adventures, the Bishop Pass Sleeping Bag helps us sleep comfortably wherever the trail leads.
