Vista 9505 Dallas Double Canopy Automatic Folding Umbrella

The Dallas engineers around the one failure every folding umbrella shares — the gust that turns it inside out. Two canopy layers sit one above the other with a vent between them, so a sudden updraft passes through rather than lifting the frame, and eight ribs hold the 23-inch span steady while it does.

It opens and closes on its own at the press of a button, and at 17½ inches closed it disappears into a briefcase or a tote until the sky opens.
