    1. Best Welterweight Bag I've ever used

      The backcountry bed is awesome. For everything other than crazy cold or wet it is perfect. Its comfortable, light and better than any bag I've ever used. I've spent hundreds of nights camping and have never once used a bag that made me feel so comfortable. I can control my temperature and move around without having to wake up and unzip my bag. This bag is incredible and I'm sad I just now bought one. Do yourself a favor and buy this bag and never look back.

      The only thing I wish was different is that they made it in an 850-900 fill down to reduce weight.

    2. For the person who hates sleeping bags

      For the person who hates sleeping bags this may be the bag for you! It was for my husband. I am so thankful for this sleeping bag, after years of years of hearing my husband grapple with his sleeping bags and curse out many broken zippers we had a peaceful nights rest. It was hard to get him up and out the next morning. He said that he even slept the whole night he was so comfortable. on Jun 24th 2018

    3. Really excited about this product

      I'm not a great sleeper, especially cramped up in a traditional sleeping bag. I tend to spend all night fidgeting, and fighting the zippers which always seem to stick on fabric somehow or another. Also, I've always had synthetic bags, and after borrowing my wife's down bag once I knew it was time to upgrade. After a few weeks of research, I kept coming back to the back country bed. The ability to sleep on your side or stomach comfortably is HUGE to me, and the foot vent at the bottom is guaranteed to be a game changer. I've only tried it out on the living room floor so far, but everything seems to work as advertised. Super comfortable in any position, with lots of flexibility for you to move your arms and body around, I can't wait to get the back country bed into it's natural habitat. Also, the down is super light, and seems really warm. on Jun 7th 2018

    4. Super light and Keeps you warm!

      Recently purchased this sleeping bag for backpacking. After researching both this sleeping bag and the cloud 20 i decided on this one as i am a side sleeper and this looked like it would be perfect for me. The weight is slightly heavier then the cloud 20, but this bag is worth it.

      Recently slept with it in about 34 degree weather and was toasty warm all night. Using the cords to secure the bag was perfect i switched from side to side throughout the night without the bag dislodging and making me cold. I do recommend a decent sleeping pad as there is no down in the back area (for good reason as you would just compress it), i am using a reflective sleeping pad with a 4.9 R rating and it does the trick nicely to keep me warm.

      The sleeve for the sleeping pad is awesome, as i move around a lot while i sleep it really helps keep me on the pad. I was skeptical at first in spending so much for a sleeping bag, but after getting this one I would make the same choice again and again. If you are looking for a light weight, warm sleeping bag for backpacking look no further you have found the perfect bag!

    5. Impeccable Product

      Having owned multiple sleeping bags, this is truly the best. Not only are they warm enough but when you do get too warm the foot pocket works flawlessly in aiding in temperature control. Zippers tend to break on every sleeping bag, which is another great appeal. It received a four as there was no four-and-a-half star. The only downfall is that you need to use a sleeping pad since there is no padding on the bottom. It would be great if they took this into account and added some padding in the main bag while still keeping pad sleeve. on Apr 18th 2018

    6. Nice but needs some changes

      Spent 2 nights sleeping in 25 degree weather and was a little cold. Felt cold on my back because there is no down fill where the pad sleeve is. Also I move around a lot and found myself hanging out of bag because it doesn’t secure well with the cord. I live the sleeve for the pad. on Dec 18th 2017

    7. Finally! A sleeping bag that stomach and side sleepers will love!

      Just used my bag for the first time in Yosemite last night. When I first got a look at it in person I thought, "Oh oh, it's a little mummyish in shape". I cannot sleep in mummy bags. Way to confined. (If it wasn't for quilts I'd have a very hard time sleeping in the backcountry. I use the Sierra Designs Backcountry quilt 30 degree 800 fill.) I was a little anxious during the hike up to the top of Yosemite Falls wondering if I'd be able to sleep that night? Especially since it was going to be much colder than we anticipated that. We were expecting a low of 41 degrees, it actually got to 18 degrees. I would've never believed that until my friend came into my tent at 3am because he was to cold in his hammock. I was actually sweating a bit. (I was wearing long underwear.) I released the bungee cord that keeps the comforter in place and was really surprised how well the comforter seals in the heat. It also made sleeping on my side no problem at all and very comfortable. I was as comfortable on my stomach as I would be using my quilt. I was even able to bend my legs comfortably.
      I use a 2.5 inch thick 20R for a pad. The fit was a little snug, but it still only took me 10 seconds to slide my pad in. That reminds me about one of the best things about the bag. It stays put on your sleeping pad. So nice not having to do the nightly readjust.
      The bag is also compressible. It was in a 15 liter compression sack with my puffer, 2 pairs of socks, beanie, and long underwear (top/bottoms). I still had about 6 literally left to use in the sack. I was able to lay the bag sideways at the bottom of my bag. It made for a perfect base. It is a 65 liter bag for reference.
      All in all this is the best bag I've ever owned. The only thing I would suggest is try to find a way to make the bungee less noticable when you're on your side. It definitely did not hinder sleep, I could hardly feel it, but it was noticeable. This will be my go to bag 3 1/2 seasons out off the year. I can't believe I said that about a sleeping bag!?

    8. Will Never Buy Another Bag!

      Holy H***! Is this bag HOT! Well, more accurately, it is warm. But never was I uncomfortable in it either. I have never used this style bag before and was extremely hesitant about buying one. But, after seeing strong reviews and having a close friend rant and rave about his bag, I decided to pull the trigger. I could not be happier with my purchase. I was camping in temps in the teens (sleeping inside the SD Convert 2) and never once was I cold in this bag. Much less, was I ever uncomfortable! I hate mummy bags! But this quilt/blanket design completely changed my world! I was easily able to side and belly sleep comfortably. The blanket top is plenty long and wide enough to keep itself tucked in on the sides and over your head if you need it. There is also a brilliantly placed detachable little bungee cord across the opening that helps keep the bag opening wrapped around you and the blanket. One thing to mention is that a sleeping pad is an absolute must as there is NO stuffing on the back of the bag from the hip up. You won't notice with a good sleeping pad though! In the end, the title says it all. This is a quality bag with a great design that will ensure comfortable sleep anywhere I go! on Oct 27th 2017
