The "Big Toe" footbox provides additional comfort and effectively makes useable space inside the bag longer.

Its so cozy right out of the box its like having my own bedding with me. I own the ronin bag as well. if im not in the backcountry or in some remote location the BIG Timber is my favorite.

    5. Most comfortable, high quality bag ever!!

      I can't say enough how comfortable these Big Timber bags are!! I ordered two in different degrees of warmth and they can zip together to make a bigger bed, or are roomy and cushy as a single. The warm flannel is extremely comfortable!! I've recommended these bags to my entire family. Thanks for the high quality products! on Dec 30th 2016

    6. Great product!

      Having been a floor sleeper for some time now I was using 3 blankets during the cold months (2 heavy ones and a light one) Until I found this sleeping bag at gender mountain. now I Only use two. My lighter blanket between the carpet and the SJK it is very comfortable and keeps your body heat from escaping thereby keeping a very very cozy environment within during cold nights.I have still to try it on the summer months when I will reverse rolls and sleep on top of the SJK. Have to mention that we used the SJK on our last trip and my wife and I slept on our futon in our Dodge promaster and it kept both of us nice and warm on a 40 degree night in OKC it makes it very hard to get up in the cold mornings I think that's my only complaint and alldough its big enough for the 2 of us to cover us , we are thinking about buying another SKJ for her. on Mar 27th 2016
