speaking from personal experience with a 3 color desert camo UK... bad choice of materials... the light weight rip stop fabric is VERY light and will blow up in a breeze (not even a strong breeze either).. not only that but being a thin 100% cotton material.. it wrinkles very easy... looks great after washing and ironing, looks great when you first put it on.. just don't move! well... walking doesn't wrinkle it that bad.. but forget sitting..

the heavier weight twills would be much better..from teh looks of it the urban camo is a heavy twill
