Andy Ricewrote a review of Marmot Astrum Jacket - Men's on November 30, 2016
Familiarity: I've used it several times
Fit: True to size
Love this jacket. With all the options out there, I opted for this one because of the stretch and the feel of the fabric Super warm for how lightweight it is as well. The shell is reasonably durable for how soft it is. I have been wearing with a t-shirt in about 40 degrees and very warm and then dropping into the low 30's and still comfortable. Lower temps than that, I have put just a long sleeve on and have been fine. It fits well. I am a medium in most everything and this fits great in that size.
