I now own three pair of this style pant from Columbia and find them very comfortable and lightweight.  I bought one pair to try them out in my normal size (32/32) but had to send them back for a 30/32.  Then I bought two more because I like them so much.  Now I keep an eye open for a good price on some of the other colors I want to add to my wardrobe.  The return was a breeze and the shipping, as always, was speedy!
