    Protective warmth from spring to fall.

    The Mountain Hardwear Ratio Sleeping Bag ensures a sound sleep from dusk to dawn so you can get the most out of your backpacking or camping trips. ThermoTrap Baffle construction secures 650-fill down insulation in smaller chambers to balance the down evenly across the entire bag, and the down insulation's Q.Shield treatment helps the down resist moisture and retain its heat-trapping loft, to keep you warm in sub-freezing temperatures. Its comfort mummy cut provides a slightly larger shape than standard mummy bags to keep you comfy without adding weight or minimizing warmth.

    Mountain Hardwear made the Ratio's shell out of dobby for durability, and the taffeta lining is smooth to the touch for extra comfort. The down-filled face gasket at the hood and the insulated draft tube across the zipper make sure you don't feel a chilly draft throughout the night. The hood features single-handed drawcords that cinch it securely around your head with a simple pull.

    Great, simple down bag.

    • Familiarity: I've put it through the wringer

    I've had this bag going on 3 years (and over 100 nights) and couldn't be happier. It packs down so small that I use it for every outing from 0°F to 50°F. I've never had an issue with the lack of a draft collar, and at 6'7" 200lbs, the long size is just right for me. In fact the only issue I have is my girlfriend trying to steal it. In a world where down bags can be ridiculously priced, this one will serve you well and not break the bank.

    Great, simple down bag.

    Pretty good bag for the price

    • Familiarity: I've put it through the wringer

    Most of my backpacking is done in the southeastern Appalachians, during both summer and winter. So, my primary concerns for a bag are weight, warmth, water resistance and loft during humid conditions. I bought the Ratio 15 last year prior to a trip in which temperatures were anticipated around 20, but dipped into low single digits with high winds and 90+% humidity. Since then, I've used as my primary bag in conditions ranging from 19 to 50 degrees. Always in a tent, though without a fly on clear nights, and pretty much always with the standard NeoAir XLite. I'm a pretty average sleeper, not too warm but not cold either.

    I've found it to be too warm any time the temperature is above 35, maybe 40 if there's no air movement. At that temperature, it needs to be unzipped and used as a quilt. From 20ish to 35, it is perfect - just had it out in the Black Mountains in a 28-degree clear night with some breeze, and I was perfectly comfortable. From 15-20, I definitely want a fleece, a hat and some long johns to stay warm, but still good- especially w/ extra clothes stuffed around my feet. Below that point, it's definitely chilly. The mid single-digit night mentioned above definitely tested its limits and I was cold most of the night. That's to be expected though, and the 12 deg survival rating seems about right.

    Overall impressions: it's not the absolute lightest down bag, but certainly does the trick for those who don't have $350+ to spend. Materials are mostly good quality though it is duck down. The down retains its loft well in humid and damp conditions and dries quickly. Fabrics seem of good quality; they're durable and I've seen minimal down leakage through the year+ I've used it. Zipper gets stuck occasionally, but that's a minor quibble. Shape is comfortable and allows me to toss and turn. Hood closure system is a little awkward, but there's enough fill in there to stay warm, at least. Overall, a very solid bag for the budget and for many backpackers' needs - just use a good pad and you're set.

    Great all around sleeping bag!

    • Familiarity: I've used it once or twice and have initial impressions

    I purchased a pair of these bags for me and my wife and was looking for the widest non-rectangular bag I can find. We are primarily car campers. This bag was very comfortable (not too tight), allowing you to move inside the bag, instead of having to move the bag itself. I alternate between sleeping on my side and my stomach through the night and this bag accommodated me well. The bag was warm; almost too warm for the nights we spent in them, which averaged about 35 degrees. However, this was appreciated as I'm sure we'll see colder temperatures in an upcoming trip. We're both pretty short ~5'4" which helped make these bags a good fit for us.

    Warm an lite

    • Familiarity: I've used it once or twice and have initial impressions

    Used it for the first time on an overnight snow shoe trip and it was great! Kept me toasty warm in low 20's all night. Looking forward to many more adventures with it.

    Great down sleeping bag for the price.

    • Familiarity: I've used it several times

    This is a great basic down sleeping bag. It is fairly warm - for me down to freezing temperatures. I see myself using it for 3 seasons. You wont find a better priced down sleeping bag out there. For a really high quality, but much more expensive option I would look into Western Mountaineering bags. This bag is 600 fill down, Western mountaineering is 850-900 down. All that means is the higher the number the higher the warmth power. But if you are looking for a great all around bag, for a good price this is it.


      Looking at either this bag or the Marmot Sawtooth 15. I like the idea of having more leg room in this vs. the Tooth, but it doesnt appear that this bag has a draft collar around the neck/shoulders. Can anyone confirm if this is the case? If it doesnt have one then I assume the Marmot could be pushed to lower temperatures than this bag would be capable. Any thoughts or comments would be appreciated!

      that is correct. the sawtooth has a draft collar and the ratio does not. I had a sawtooth and used it quite a bit then returned it because it was leaking feathers like crazy. They may have changed the outer fabric since i had mine. i returned it and am getting the ratio. honestly i like the simpler design of the ratio and i think the difference is negligible as far as the draft collar. the ratio actually has a lower en rating. But the outer fabric of the ratio feels like a much better quality. Thats my two cents anyway

      Solid sleeping bag!

      • Familiarity: I've put it through the wringer

      Male; 6' 1"; I run hot; Purchased the "Long" size.

      The bag was too long for me--that's my fault for not researching properly so I didn't dock any points. I used this bag kept me plenty warm on a 20 degree Fahrenheit night while wearing long johns and a long sleeve merino shirt. Keeps its loft nicely and packs down super small. Zipper seems to be solid and hasn't shown signs of wear.

      Mountain Hardwear Ratio Sleeping Bag

        Re: Mountain Hardwear Ratio Sleeping Bag, 15 degree down. I bought this bag as a three season bag, but I wanted to test it at colder temps to find out about its limitations. I set up my Army cot outside and placed a Thermarest


        • Familiarity: I've put it through the wringer

        Warm, very warm. Even when wet. Been using it for the last 100 days on an adventure that started in Red Rocks, Nevada climbing in the winter (read: snowing.) with nighttime temps right at the threshold of the bad (15-10F), I was always hot. But to be fair, I run pretty warm. The bag next traveled with me to Argentina for 5 months where I used it everywhere from Northern Patagonia after days ice-climbing and fishing, to basecamps on Aconcagua and Mercedario (northern Argentina). Just sleeping on top of this thing I can be pretty warm for a night. I regularly use it as a comforter with the bag unzipped all the way, and just my feet in the small foot-pod.

        First of all I decided to ditch a synthetic bag for this down bag, the difference in price is pretty big but so is the difference in quality. I chose the Ratio mainly for the pack size and pack weight and I stuffed it in an Alps Mountaineering small compression sack and as you can see in the pic here its a tad bigger than a football. My pad is right under it, its made by Stoic and there's a water bottle and a weatherman so you can see the size of the bag in that stuff sack. I purchased this for a trip to Iceland and I slept in my skivvies in temps around 30 degrees and it was awesome. We had temps all over the place and not to mention crazy wind and rain and I could not have been more toasty and comfortable. I purchased the long and I am 6'1 and around 175 with an athletic build. I never felt restricted and I had plenty of room for a pillow in the head cap. One of the nights the foot of my bag was pretty wet because the rain soaked through our rain fly and within an hour or so it was dried out and worked fantastic for the rest of the trip.

        If there was something I would change it would be the way the drawstring works to seal up your face, its a bit difficult to customize how it closes but its nothing too serious to fret about. The zipper is like any and all sleeping bag zippers, and much like my Auntie Freeda, it has its on days and off days.. it got stuck every so often but it worked. All in all this bag was a life saver!
