Why We Like It – Wester Mountaineering Summerlite Review

The Western Mountaineering Summerlite Mummy 32F gives you every reason to go outsides and sleep under the stars, thanks to its comfortable design and performance, even against colder weather.

  • Great for spring, summer, fall, and first half of winter
  • Compact and portable
  • Available in various sizes
  • Not ideal if you have claustrophobia
  • Expensive


To bring you its great performance is 12 denier shell fabric that adds durability and water resistant properties. Then it fills it with 10 ounces of 850 plus fill power goose down, giving it awesome fill weight. In other words, it’s tough against weather—especially when you need to be warm in the most crucial of times: when you’re asleep. With its continuous baffles, you’ll have the option to maneuver down within the sleeping bag. This can be helpful if you’re dealing with colder temperatures and need to add some extra warmth to your feet.


You might be wondering about the Western Mountaineering Summerlite Sleeping Bag’s shape. If it’s name didn’t give it away, it was designed to look similar in shape to an ancient Egpytian sarcophagus. It incorporates this shape to hug your body snuggly, preventing heat from escaping, but keeping shoulder girth wider so as to not restrict movement.

The Summerlite weighs only 3 pounds. It isn’t the lightest bag, but on par with mummy bags such as Teton Sports Leef 0 or the Winner Outfitters Mummy. It comes in fives sizes: 5’6” Left Zip and Right Zip, 6ft. Left Zip, and 6’6” Left Zip and Right Zip.


There’s plenty to like about the Western Mountaineering Summerlite Mummy 32F—its insulated draft tube blocks weather from coming in at the zipper, comfortable, and keeps you warm. In other words: everything you want out of a sleeping bag. It’s even water resistant, lightweight, and comes in various sizes.

All things considered, this sleeping bag Western Mountaineering Summerlite releases has good value. However, the sleeping bag is really expensive. In fact, compared to sleeping bags like the Winner Outfitters’ Mummy, it’s a pretty heavy price tag. If you want near identical performance, the Mummy from Winner Outfitters is a better bargain. Better yet, the Outdoor Vitals Summit 0°F performs even better at half the price.

Wester Mountaineering Summerlite Review Wrap Up

There’s no doubting the Summerlite Mummy 32F; Western Mountaineering designed another quality sleeping bag. Its price can steer people away, but Western Mountaineering enthusiasts won’t be disappointed. In return you get an excellent sleeping bag for use most of the year (excluding the coldest time in winter), available in several sizes, and it’s portable. As long as you don’t mind the restrictive shape, you’ll love it.
