MyCanopy by Rio Beach snaps easily onto most chair frames to provide just the right amount of personal shade. SPF/UPF rating is 100. The canopy folds up easily while still attached to your chair and folds flat with the chair for easy transport. Canopy locks in place and is surprisingly sturdy in the wind. A great addition to any chair and good for you, too! 80958318020 RIO-TSBCAN
