I have slept in over a hundred sleeping bag types, and prior to this one my favorite was the military extreme cold bag. But it weighs 11 lbs and is big, heavy and awkward to backpack with. But, warm and comfortable.
However, because I could not see what could be done to a sleeping bag to make it worth that much, I was not willing to pay $300 + for ANY sleeping bag; this was given to me as a gift. Today, if anything happens to that bag, I won't even flinch at paying $350 for a replacement.

Though I have not slept in it to -15 deg. yet, I have tested it 'outside'. to 0 deg. It is the most comfortable bag I have ever slept in. Unlike the military bag, that bunches to your clothing, this bag seems to just slide up and enfold you. Most bags have a few minutes waiting period, that your body must shiver in to warm it up, but not this one. As soon as you're in, you're warm!

There was an outing in which I took my two Boxer dogs with me. I woke up in the middle of the night, and despite them having a thick blanket and each other to snuggle to, they were both shivering. I unzipped the 'draft tube' to make more room then unzipped the bag and invited them in enough to just lay a part of the bag over them, with me in it. Their bodies blocked the cold from me and we ALL slept toasty that night.

The weight and size of this bag when compressed is quite adequate for backpacking, though as any backpacker will attest, the smaller, the better. I carry a hammock and ponchos for shelter (as I'm 56 yrs old and can no longer sleep on the ground due to my back) and sleeping in a hammock is true testimonial for a quality sleeping bag, since you have the wind blowing above AND below you. Of course there are ways around that for a seasoned camper, but I have never had to implement them yet.

I have nothing but praise for this bag!
