Jameswrote a review of Marmot Trestles 15 Sleeping Bag: 15 Degree Spirafil on August 23, 2011
I have used this bag since 2004, numerous times, 60 plus nights.
Very soft and comfy, durable, easy to wash and dry. I am 5'9" 150 lbs and love the tight fit of this bag. Helps to eliminate cold spots.
Good at 50*F, not too hot, Too warm(?) above that.
In the winter of 2005, on the Current River, Christmas, it got down to 5*F, snow on the ground. I slept very well with an R 4.5 pad, long johns and a 200 weight fleece top for three nights.
Many nights spent on snow at 20*F.
This bag cannot be beat for the money.
