Product Reviews

I have one of these that I've been dragging up and down the trail for a couple years now - still looks new. This bag is unquestionably soft, warm and roomy. It lofts up like you wouldn't believe. It's truly a pleasure to sleep in, and I'm guilty of taking it out in weather that went below 10 degrees. I slept in wool baselayer and down jacket, but I was warm. All my water froze solid that night. I've also been in my tent on top of a mountain in a 6 hour epic downpour- again, warm and dry. I've even used it in the summer, I just unzip. I do wish it would compress just a teeny bit more, but that's probably pushing it. Quality zipper/hardware too. Would buy again but this one looks like it will last a good while. Review by Terry
Fantastic bag
Roomy and warm for a six foot, 200 lb guy in the high country of the Sierra Nevada. Not much in the way of bells and whistles by today's fancy sleeping bag standards, but a solid build and warm enough to sleep out at altitude.
It just finished its third year of 20 to 30 days out and the thing looks brand new. Not bothered by dew or a light mist. Review by Cozy Sleeper

i have used this bag a few times and am very happy. packs to the size of a hunny dew and loft in just mins. Review by gregory p
