This double-canopy umbrella features the Vortec venting system allowing air to flow through between the canopies and will keep the umbrella from inverting in high winds. The fiberglass shaft, ribs, and nylon canopy give you a sturdy, yet lightweight construction. This umbrella is great for everyday use around town, on the golf course, as a spectator out in the elements, or just walking to the mailbox. Includes a matching nylon sleeve for easy and convenient storage, when not in use.
