Seattlegal wrote a review of Outdoor Research Backbowl Pants - Women's on January 26, 2012
I am 5'8'', a fit size 8, with a fairly long inseam (I usually wear 33"-34" pants) and the Backbowl pants in Medium fit me perfectly. They certainly provide ample room for a layer of long underwear, but I wouldn't call them bunchy or slouchy. If you're really slender, though, they might not fit you as well, and I can see how the legs might be long on shorter gals. I love the fit of these pants and the pewter color is great.
