Available information at the time of purchase led me to believe that this would be a great bag for the money. Wrong.

I just spent two chilly nights in it on the Wyoming plains. The temperature never fell below 28-degrees F. Even while wearing capilene and socks I could not keep warm! The zipper was also a constant hassle. I almost had to cut myself out of the thing because the zipper was constantly stuck in the fabric.

Spend a little more money and buy a quality bag. This cheap import is not the ticket.

I have used this bag for 12 nights now and on all 12 nights I am very satisfied with it. I am a cold sleeper, on 3 nights the weather was in the high teens to the low 20s and all I needed to keep comfortably warm was a pair of socks.

It is a very spacious but not too big also the extra short zipper is nice on thous warm nights. It seems to be a well made bag that will give me good service for several years. Also this bag lofts very quickly after being compressed in the stuff sack.

I would definitely recommend this bag to a friend.

After much research I decided on this bag for use on the Inca Trail in may for two reasons; even though I'm skinny I like a lot of room and I had good experiences with other Marmot products.

I usually sleep warm and on one night we had -8C and all I needed were light thermals and this bag. There is plenty of room to turn and move around for a 5'10" thin build. Most of the other nights were slightly warmer and I had to open one or both of the side zips to cool down.

On the negative side - the zips get caught even if you're being careful and the stuff sack is a little small. I can't speak for the heat retention of the bag when wet but it certainly did all I asked of it.
