Summary
Praised by OutdoorGearLab and mentioned in Reddit's top 25 most-recommended bags, the Bishop Pass 15 hits a sweet spot between performance and price. A 15°F rating makes it a versatile three-season and shoulder-season pick.
The top recommendation for budget-conscious campers in r/CampingGear. A 20°F rating covers most three-season trips, and REI's quality control and return policy make it a low-risk first serious sleeping bag.

Cons
- Heavier than premium ultralight options from WM or Feathered Friends

Our take
Mountain Hardwear doesn't get the hype of Western Mountaineering, but the Bishop Pass 15 earns its spot in OutdoorGearLab's top 10 for good reason — it's a serious bag at a price that won't make you wince.
Not everyone needs a $500 Western Mountaineering bag. The REI Lumen 20 is the smart buy for casual backpackers — solid warmth, reasonable weight, and REI's legendary return policy as a safety net.
