This new dark green 3-in-1 UV Umbrella, Bivvy and Shelter features a metallic UPF50+ UV protective inner coating. It will block the sun’s harmful ultraviolet rays and protect you from rain, wind, and sun. The 3-in-1 UV Umbrella Bivvy Shelter has a two-piece coated steel shaft. This incorporates an angle tilt mechanism and a thumbwheel twist-action height adjustment clamp. On the underside of the canopy, there is a long zip which encircles about 3/4 of the canopy edge. This is used when the umbrella is configured as a shelter umbrella to attach the wind shelter panel with its two clear PVC side viewing windows. There are also two shorter zips, one on each side.
