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
Rated 5 out of 5 by Love this bag! Purchased this bag along with Heratio 15 (for wife) for use in the Cascades during the winter. Bag is warm, compresses extremely well, light and it is very comfortable. Favorite bag ever. A fantastic buy for anyone who loves to spend time outdoors year-round. July 6, 2014
Rated 5 out of 5 by Great bag at a good price My wife and I each purchased a Ratio and Heratio sleeping bag for hiking the Inca Trail to Machu Picchu. Right off the back I really liked this bag. Our first night on the trail there were lows in the high teens. I stayed completely warm the entire night. The bag is spacious in the right areas. I am 5'9'', weigh 160 pounds and have the room to sleep with bent knees. I have had 15 degree bags in the past that have failed miserably. So far I have used the Ratio about 9 times and have been more than pleased every time. The Ratio is a highly recommended product. June 21, 2014
