A 600 fill down sleeping bag for winter and mountaineering use. Stretch box baffle construction design, which minimizes shifting of down and cold spots. Includes full draft collar, stuff sack, and storage bag. Click here for REI's product info on this bag.
I bougth the Down Time -20 model back in 1994. Since then, the -20 model has been discontinued and apparently replaced with the -10 degree model.
It's probably the same bag anyway, as I was always a little leary of the -20 degree rating. My bag has less loft than other bags of similar temperature ratings, so I probably wouldn't use mine in anything below -10.
I used my bag on several winter trips in Colorado, and on Iztaccihuatl, Shasta, Rainier, and Big Bend in December. I never felt cold, but the temperature never got near the bag's rating.
Overall, this is a good down bag for the money. It stuffs and compresses to a pretty small size and usually regains its loft in virtually no time.
My only complaint is that, on the bottom of the bag, some of the down has migrated to the sides, leaving a few places where there is only two layers of taffeta between me and my ground pad. I've tried to shake it back into place to no avail. Mind you, though, my bag is about 9 years old now.
I bought this sleeping bag this past September 2004. It has proved to be a warm, packable, and extremely durable bag. I have used it on several trips in Colorado this year without ever being cold. I would highly recommend this bag for anyone looking to break into the winter camping/mountaineering/winter backpacking area of wilderness travel. It is affordable and it performs like sleeping bags twice its price.
