An Umbrella may keep you safe from the sun, but what will keep the umbrella safe from the rain? Unless you've got roof over your umbrella (in which case, why do you have an umbrella?), you'll need a cover.
Treasure Garden offers a wide range of covers designed for their cantilever-style umbrellas. The CP912 cover is designed to fit their AG19 and AG3 series of umbrellas. The RHINOWeave technology is entirely water resistant, allowing for top-notch protection.
