Western Mountaineering Ultralight Review

"Excellent bag. Kept me warm @ 11,000 ft in the CO Rockies with temps down into the 20's. I'm positive the 20 degree rating will hold up easily. at 30 degrees I had to vent. Only problem is the hood is not very deep, but once I get positioned I'm comfy all night."

"I invested some time looking for the right bag and this bag fit the bill. I was looking for a lightweight down bag ,that packs small and would keep me warm. I’ve only been in 40 degree weather but I had to sleep in the nude cause I was so hot. It’s weighs only 1.9 oz and compresses to just under the size of a football. Comes with a draft collar that keeps you nice and toasty and the no stick zipper is a dream. For 3 season camping there are no negatives. I would even take it on most winter trips."

"I purchased this bag based on reviews. It lives up to lofty expections so far. In the year I've owned it, many nights in freezing temps with no problems whatsoever. Many times I was too warm and had to unzip. I've grown attached to it although I'm detecting a slight reduction in loft. This may very well be due to the harsh conditions and the poor care that I've given it."
