I don't know about you, but I get tired of trying on clothes that are supposed to be size medium (sleeves, shoulders and neck fit great), but are cut so large through the torso that it makes me look like a flying squirrel.
While the one-size-fits-all cut may save camping gear manufacturers money... they fit terribly. Also, because of the extra fabric, the clothing not only looks unattractive it gets in the way. If that's been your situation too, have a look at one of the best pieces of hiking equipment Columbia has to offer...Backcountry, a great store I highly recommend as you already know, has the Men's Columbia Clothing Ballistic Vest (there aren't any Women's Columbia vests that I can recommend wholeheartedly at this time). It addresses bulk with what they call their "authentic fit". If you're somebody that likes vests because they eliminate bulk and make it a little bit easier to move you'll probably want to take a look. The microfleece keeps you warm on cool days, and if it turns cold you can just zip it into a compatible Columbia shell with their Interchange zip system.
