You can't find a better 10 degree bag.
Incredibly lightweight, this sleeping bag stuffs down to a manageable backpacking size. When taken out it lofts up, lofts up some more, finally forming a thick, soft lightweight cocoon. The draft collar is well designed and chafe-free, and the hood cinches down easily. The zipper anti-snag device is the only one I've ever seen that works every time.
This is a VERY warm bag, rated at 10 degrees. I've been at freezing temps in strong winds on a high ridgetop and was way more than toasty.
Sure, it costs more. But it's made in America, the craftsmanship is unequalled, and you'll never be stuck wishing you had packed a better sleeping bag.
