Why We Like The Alpinlite 20 Down Sleeping Bag

Climbing or traversing technical pitches with a massive load dangling behind you is a bad way to go through life. We recommend the Western Mountaineering Alpinlite 20-Degree Down Sleeping Bag for alpine climbers and weight-obsessed backpackers who demand top-shelf quality and bottom-line weight savings.


We love how its 850-fill down insulation boasts one of the highest quality loft-to-weight ratios around, meaning it's surprisingly warm for how little it weighs. Western Mountaineering wrapped this insulation around a highly breathable shell to keep the down light and lofty when you're sleeping in a tent under a rainstorm.
