Nice details, warm with 750 down, but size runs big! - Mountain Hardwear StretchDown RS Jacket - Men's

I generally really like the quality of MH product, and this jacket has some nice features with external zipper and pockets. However, I gave it four stars because the outside zipper is fairly useless with a backpack, as the shoulder straps don't allow for access. Also, and the main reason I had to return this is that a size small fits like a medium. Even compensating for the " stretchdown " aspect, the shoulders and arms were big on me in a size small. I'm 5'7", 36 chest.
