My climbing partners and I trudged into camp around noon on Mt. Rainier, and I immediately tore off my boots. We’d been on the move since 9 p.m. the night before — a 15-hour push to the summit and back from a low camp. I dragged myself into my Western Mountaineering Alpinlite sleeping bag and plunged into what felt like a 5-hour coma — quite possibly the deepest sleep of my life.
That quality of sleep felt like a trend while I was testing the Alpinlite. Was it because of the bag’s high quality down and roomy interior or more a result of my pure exhaustion every time this bag accompanied me into the backcountry? Probably a little bit of both. Regardless, the Alpinlite has been just right for backcountry sleeping from shoulder season through summer in the mountains.
Western Mountaineering’s Alpinlite sleeping bag hasn’t changed much since I tried to convince a customer I could stuff it into a Nalgene when I worked in retail a decade ago. Since then, it’s been a mainstay in GearJunkie’s Best Backpacking Sleeping Bags. So, I stuffed this long-standing fan favorite into my backpack and headed into the mountains.
In short: Western Mountaineering’s sleeping bags are light, handmade, simple, and downright premium. The AlpinLite is their 20-degree offering, which sports a full hood, offset continuous baffles, and 21 ounces of top-quality 850+ fill goose down, all wrapped in a roomy yet ultralight 12D ripstop Nylon shell. I put this poofy bag to the test over the spring and summer in Colorado’s snowy backcountry and in the Cascades, and man, did I sleep well.
