The Silverback-Long, with its enigmatic question mark handle is 33 1/2" (85cm) from handle to tip and has a diameter of 42" (107cm). The Silverback-Compact in comparison is 11" (28cm) in length and has a diameter of 38" (96.5cm). Both of these unique and stylish umbrellas are AUTO OPEN / AUTO CLOSE. This means they can be both opened AND closed at the touch of a button. Press the button once to open and then the same button again to close - then simply compress the shaft ready for the next occasion. This feature, as well as impressing your friends and family, also helps people with a disability in one of their arms or hands. The long version has an innovative tensioned cable technology combined with flexible fibreglass ribs and hexagonal section chrome shaft making it surprisingly strong in the wind. The compact version also has lightweight and flexible fibreglass ribs and has a good quality chrome shaft and multi-link frame. The silver lining is intended to reduce the amount of Ultra Violet getting through the canopy. One slight drawback of this approach however is that some UV can sometimes be reflected from the ground (depending on the surface) and then again from the reflective interior of the umbrella onto one's head and face. The parabolic shape of the umbrella can actually have the effect of concentrating the UV rays onto ones face. To combat this we have inverted the conventional UV protective design so that the silver is on the outside and the black on the inside. This maintains the benefit of filtering out much of the UV strength and reflecting it away from the outer canopy surface. However by having a black interior we are able to stop the sun's harmful rays from being focused on the user's head and face. Umbrella weight 570g.
