Samantha Crowwrote a review of The North Face Dolomite Sleeping Bag: 40F Synthetic on October 27, 2019
Familiarity: I've put it through the wringer
I bought this sleeping back about 6 weeks ago and have used it pretty extensively. I love the rectangular design and love the materials it is made out of. It keeps me warm in the mid to low 40's. I used it one night while hammock camping with a 15 degree underquilt and stayed warm at 42 degrees with no chilly spots. I also used it on a weekend with temps ranging from 44-48 degrees with a 3.3 R value mat (rated to 15 degrees) and was toasty and warm with no worries. I would push the rating on this bag even two or three degrees below 40F with the right clothing and camp mat/underquilt because it is just so warm and reliable.
