I'm right with your about the powerstretch. I am constantly amazed by how WARM this stuff is, in spite of its relative thinness. Mountain Hardwear clothing, however, has never fit me very well. I wear a medium in most manufacturers and when I tried on the medium of this shirt in the store, it fit me well. However when I got it home, the sleeves were too short and the collar seemed too tight. I brought it in to exchange it, but the large seemed too billowy to use it as a base layer. I ended up sticking with the medium and mostly use it underneath some other layer, so the slightly exposed wrists can be dealt with. The one thing I really can't live with, though, is the reversibile zipper slider. That thing rests right on my adams apple when its zipped up and it's really uncomfortably tight there--and it's not like my neck is any bigger than average.
