You need the lightweight, PFC-free, mummy-style NanoWave 25 Sleeping Bag to keep you comfortable around 25°F. Synthetic SpiraFil High Loft Insulation will keep you warm even when things get wet.

Not as warm as advertisedWe bought this bag for our daughter and were surprised by its thinness. We just took a trip to Lassen where the nights were 35-40 degrees F. My daughter complained of being cold the first night, so she and I switched bags. I was freezing every night of the trip even with all of my warmest clothes on. We were backpacking and did not have the ability to add more layers or switch out gear. I hope that Marmot changes the temperature rating on this bag. Even with temperatures at the level they say should be comfortable, this bag did not keep us warm enough.

Disappointing. Thin. Not as warm as advertisedVery disappointed. Advised by Marmot online as -4C, when arrived product label said comfort -3.4C and limit-1.9C. On a Sydney winter night of 9C, inside a house on the top floor and laid on a bed, I was dressed in wool thermals and a fleece hoodie, and still felt cold inside the bag after 15min. Had to put a blanket on top to fall asleep. I'm 160cm and 51kg. Now I have to spend extra on another sleeping bag that's adequate for my upcoming Nepal trip.

Not warm. Too big. Sad.Marmot messed up big-time with this one. As other reviews have noted, it didn't keep me warm even in ~40 degree weather. Brought this on a week-long excursion in Utah and Colorado and was downright SHIVERING every night, even though it only dropped to in anything below 36, unable to sleep, even with my down jacket and wool socks on, with the bag "sealed" shut over my head. I imagine you'd freeze in 25 degree weather! Hoping I can return this.
