Best gear purchase I've ever made. The bag is warm, compressible, and lightweight.... 3 traits generally not possible to achieve together with synthetic fill bags. Yet somehow Mountain Hardware pulled it off. The construction is excellent. The zipper configuration is genius. The zippers themselves ... Read More

    Just received bag and only used it once so far, on two-night hiking campout. Bag weight and compression size were good for the hike, tight but no problem fitting it inside the compression bag. In the low, low 30s first night, warmer but rainy the next night. Plenty toasty both nights, but did add a thin bag liner the first night. Could feel the difference immediately from my bargain basement 20 degree bag. Didn't feel like the bag picked up any appreciable moisture even though it rained hard all afternoon and much of the second night.

    Good bag. Delivered the warmth needed on the trail. A little snug in the fit, however, that's the compromise in getting an ultra light sleeping bag.

    Bag is nearly perfect. Compresses to the size of a soccer ball. Extremely light weight and warm. Material is very durable. Zippers are my only issue as the zipper flaps get caught too easily in the zipper.

    I just took this sleeping bag camping and it performed very well. Temps went down into the 30s and the sleeping bag got wet down by my feet and the sleeping bag still kept my feet warm. Very light and compact.

    The sleeping bag is pretty much what I wanted. A three season bag that was light and warm. It has some room in the foot box, and I like the longer zipper on one side for quick exit. I am 6 feet tall, and the regular length bag is more than long enough. My only complaint is the compression bag. It is difficult to compress the sleeping bag to fit, and it feels like it is about to split open when you do. I have not had a chance to try it in cold, but It feels like it is well insulated.

About Mountain Hardwear

Starting back in 1993, a small group of outdoor industry mavericks broke away from the pack to follow a less-traveled path. From the very beginning, the primary goal of Mountain Hardwear was to create an outdoor gear brand with a sharp focus on technology-driven design, superior performance and hardcore reliability. The result of this function-first mentality has been an array of incredible Mountain Hardwear jackets, clothing, tents, backpacks, sleeping bags and accessories. Today, after more than two decades of industry-leading innovation, Mountain Hardwear continues to set new benchmarks for dependability in the toughest conditions on the planet.
