Bishop Pass Windstopper Sleeping Bag: 0F Down

What Our Gearhead® Experts Are Saying:

"I took the Bishop Pass Windstopper 0F on a windy, cold high desert trip and it completely shut out the gusts and chill. The GORE-TEX WINDSTOPPER™ fabric is a game changer—lightweight, but built to hold warmth even in howling conditions. And it still packed down better than expected for a 0-degree bag."

When the mountains are calling in subzero temps, we trust the Bishop Pass Windstopper 0F Sleeping Bag to bring warmth without compromise. Designed by Mountain Hardwear for backcountry minimalists who venture into harsh, alpine terrain, this bag strikes a perfect balance between warmth, weight, and weather resistance. The 650-fill down insulation delivers excellent compressibility and warmth-to-weight efficiency, while the GORE-TEX WINDSTOPPER™ shell locks out wind and moisture with breathable protection ideal for exposed ridgelines, frigid tent nights, and high-altitude bivvies. Technical features like the shaped draft collar, adjustable down-filled face gasket, and footbox contour keep body heat sealed in where we need it most. We love the anti-snag YKK zipper for easy entry, and the included compression and storage sacks for flexible packing and long-term care. Engineered for performance, this bag keeps us dialed on alpine routes, winter summits, and shoulder-season backpacking in unpredictable weather.
