Intro to the Western Mountaineering UltraLite Sleeping Bag
There are few things more important than your sleep system when you’re in the backcountry. Your choice of whiskey and whether or not your tent-mate snores can make or break a trip, but a bad night’s sleep can turn you from John Muir to the Crypt Keeper in a flash. Luckily, the Western Mountaineering UltraLite down sleeping bag is here to save your hide.
Tough, super light, warm, and compressible, the UltraLite comes in as our Premium Pick for the Ultralight Backpacker.
At 29 ounces for a 6-foot bag which is rated to 20 degrees (Fahrenheit), we feel the UltraLite classifies as ultralight, but diehard gram counters might disagree. Quilts are the rage with many Ultralight Backpackers, but the design features, comfort, and easy use of sleeping bags still make them more accessible to most backpackers. If you’re willing to spend upwards of $400-$500 on a sleeping bag or quilt, we think a bag is a better investment. Also, if you have milder weather, we feel the Western Mountaineering SummerLite is your best bet, which is a fully-featured bag rated to 32 degrees that comes in at just 19 ounces, and has the same construction as the UltraLite.
