Rated 5 out of 5 by Great 3 season bag I recently circled Mt. St Helen's and this bag preformed perfect. I was more than warm on the crisp night. Not only was it warm but comfortable. After walking for 14 miles to crawl into something that is comfortable is priceless. My only ask would be for some kind of a strap to keep from sliding off the mattress. July 28, 2016
Rated 5 out of 5 by Very Versatile Bag This bag was the first step up for me from a generic, rectangular camping bag and I am so glad I picked the Ratio! I've used it a couple times while car camping as well as during backpacking and the Q Shield Down has always retained the warmth I've needed even during some winter months! This spring I was wondering how the Down would hold up to some major morning dew, but though the exterior was somewhat damp, I remained dry and comfortable.I recommended the bag to on of my colleagues who now owns one and would wholeheartedly agree with this review!

Rated 5 out of 5 by Comfort and Packability Bag is cozy warm in 30 degree temps and not sweltering when the sun starts to warm up your tent. Packs down into a 8L dry bag and fits nicely in the nose of my kayak. Stoke to add this to my arsenal of great outdoor gear. June 8, 2016
Rated 5 out of 5 by Great Bag bought the bag to stay warm while camping during colder times, researched around choose this one based on reviews - held up to the other reviews. Just took on a trip where it was rainy/snowy and cold unexpectedly - kept me super warm, dried out quickly when wet, light and compressable. Loved it. very happy with the purchase May 19, 2016
Rated 5 out of 5 by awesome I love this sleeping bag! I used with backpacking with a wind chill of -14 and was nice and warm while I was sleeping. Its light and packs down so its quite small and doesn't take up too much room April 20, 2016
Rated 5 out of 5 by Excellent bag I looked and looked, compared and looked again. I finally found the Mountain Hard Wear ratio 15. Perfect bag for me, the weight, warmth and price are unmatched. February 24, 2016
Rated 5 out of 5 by Outstanding Sleeping Bag For Both Genders My wife and I recently took a multi-day camping trip in Canada. We bought her a Heratio 15F bag and I bought a 20F bag from another manufacturer. Nighttime temps were in the low 40sF. She was comfortable in her underwear and bare feet; I could not get warm until I put on long underwear and socks. And one of the cross compartments was devoid of down, I assume a manufacturing defect. Anyway, I just bought a Ratio 15 for myself, and compared it side-by-side to the other bag. I was stunned at the vast difference between the Ratio and the other bag! Better outer shell, more down, puffy right out of the sack, etc. Then I crawled in and Presto! Immediate warmth! Now I can join my wife sleeping in blissful warmth. Thanks MH for a wonderful product! August 20, 2015
Rated 5 out of 5 by Lightweight and Warm I wanted a lightweight, waterproof bag. My last bag was synthetic and when it gave up the love I decided I wanted a down bag. I couldn't be happier with this purchase. It fits, it's warm, and it's lightweight. I woke in the morning after a 35 degree night and there was condensation all over the inside of the tent. I was warm and dry inside the bag. May 19, 2015
Rated 5 out of 5 by Great bag! I got the Ratio 15 and my wife got the Heratio 15 this past spring. Really happy with the bags! They pack down really small in a compression sack and are very comfortable to sleep in. Really love the feel and quality. Came with a really nice mesh storage bag as well.

Rated 5 out of 5 by Solid Bag I backpack and camp and wanted an overall colder weather bag without the bulk of a 0 or negative degree bag. I live in Nashville, TN so it doesnt get super cold here in the winter but we will see 20s at times and maybe a little less with some wind. I have used this bag twice now this fall and absolutely love it. It has great loft and holds heat really well. The first time I used it was on the Fiery Gizzard Trail (everyone should check out) as a simple one night overnight. I layered up just incase since the temps were supposed to be low 30s high 20s. I was stripping off layers in the middle of the night because I was so warm. With a compression sack I got this bag down to about the size of an ENO double delux hammock (maybe a doublenest). The second time I used it was in the backyard with some friends on a chilly night. Instead of using a tent I used my hammock and underquilt. Again the bag exceeded my expectations and previous 15 degree bag experience. I am excited to try it out in some of the wet times of the year to see how the loft holds when damp and truly test the repellant tech. The asthetics of the bag are also appealing. Its a nice quilt design and the bag is a solid blue color. It wont be an in-your-face style bright but it is pleasing to the eye. November 12, 2014
