I found some in a store and tried them for fit, they fit just the same as my other clothes. I like my vests to fit a bit snug and will order it a size smaller than the jacket.
To answer your question (is it worth the rave?) For performance fabrics in good camo I think it looks real good, lightweight, tough and quick to dry. The other clothing I use for backpack hunting works well but I spent hours cutting it apart and tailoring it to be functional in the mountains, installing pit zips and a lot of other alterations, Sitka gear is the closest I've ever seen to the clothing I spent months making and of course looks professionally built instead of hacked together.
