I have been skeptical of MH for the past couple years and had turned to other brands, but decided to try this jacket out because I had heard so many good things about it and it's predecessor, the Torch. I am very impressed with the fit of this piece. I have a climber build and am 6'O" and am borderline between medium and large in most brands. Since I have a thin build, large is usually huge in the chest and mediums are too short in the torso. I actually held off from buying MH's Torch jacket because it was cut too short. At 29" in length the medium is a great fit and is snug throughout the body with enough room for a base layer. As this will be a skiing and climbing jacket, I don't expect needing any more room for layering. The sleeve length is generously cut. The elastic thumb holes will come in handy when active and tuck neatly up the sleave when wearing around town. I have ran in the jacket and really appreciated the pit zips to cool down. Overall, I am very impressed with the jacket so far and am looking forward to using it for its purpose on a climb very soon.
