Western Mountaineering Summerlite Review

Likes
The Western Mountaineering Summerlite is the lightest fully featured summer weight bag we reviewed. At nineteen ounces this bag is a solid option backpacking, bike touring, and fast and light climbing. It provides the warmth necessary for these activities without sacrificing comfort. 850-fill down, a superlight shell material, and an efficient, trim cut will keep you warm and comfortable in summer conditions. Many summer weight mummy bags skip the full length zipper. But the Summerlite does not, and we like this because the bag is more comfortable in warm temperatures.

Dislikes
If you're reading this review you're probably looking for a lightweight bag for three-season use- a bag that prioritizes weight savings. After testing nearly 70 sleeping bags of all types we've found that quilt style sleeping bags are much warmer for their weight, and more versatile than traditional sleeping bags with attached hoods and zippers. We highly recommend quilts for all weight conscious three-season applications because we believe they perform much better than the Summerlite if saving weight is a priority. Warmer, lighter, and more versalite… a win-win for most people. Consider the Katabatic Gear Palisade. However, if you want a top-tier bag with an attached hood and full-length zipper, the Summerlite can't be beaten. It's the best in its class of traditional style summer weight bags with a full-length zipper.

We believe that most people will be better off with an ultralight sleeping bag.
