For a compact, automatic umbrella that won't blow inside out, nothing beats the Windpro Auto Umbrella.
Its flat-frame construction makes it easy to pack, and specially designed vents allow wind to escape, preventing it from blowing inside out during gusty conditions. Has a 43" arc, black steel shaft, fiberglass ribs, and a rubberized handle. Opens and closes at the push of a button. (11 x 3 x 1 1/4"; 12 oz)
