The Video shows how our flexible ribs allow the wind to raise the canopy to relieve the pressure to save the frame from breaking. In super strong gusts, the fabric can actually release from its "Flex-ribs" to further reduce the pressure on the frame. The fabric cannot come off the frame completely & the Flex-ribs can be re-inserted in a few seconds after closing the umbrella. Best of all, in the unlikely event of any damage, all parts are available for individual purchase, rather than needing to replace the entire umbrella. Call for details if needed. This feature is available only on our 8 x 8 size at this time.
