Marmot EcoPro Sleeping Bag: 15 Degree Synthetic - 2009 BCS

I used this bag on a few backpacking trips this summer and use it as my couch surfing bag when I travel. It is really well designed, with a lot of little features in the head area that make sleeping more comfortable and keep the cold out. The little pocket and the glow in the dark zipper pull are also nice features that you may not find on other bags. There have been complaints that this bag isn't actually comfortable at 15 degrees. If you do some research on the Marmot site about this bag

you will come across what the rating numbers actually mean. The 15 doesn't mean that this bag will perform excellently at 15 degrees. The temperature ratings that Marmot gives for this bag are as follows.

Comfort: 29.3F / -1.5C
Lower Limit: 18.3F / -7.6C
Extreme: -13.9F / -25.5C

I was hoping this bag would work great...and it just DIDN'T. The material is really slick and comfortable and the design is on point (the glow in the dark zipper pull is a plus) but the bag had me cold at temps in the 30's. To agree with other reviews of this bag it just does not live up to its 15degree rating. It is a comfortable bag though with enough room to sleep in (i'm 6'0" 190). Footbox is larger than most bags i've owned! It does compact pretty small if you use a compression sack. Bottom line...use this bag for warmer weather not the 15degrees Marmot says

I just used this bag on a early season snowy trip up Pikes Peak and during a blustery storm with temps in the low teens, the bag just worked. It's a little tight around the feet, but overall was a good fit (I'm 6'3x190). The stuff sac is a bit tight, but it works. The 'Eco' footprint is cool too.
