Blunt Lite Aqua Blue RTS Compact Collapsible Umbrella Light. Authorized dealer-warranty is valid. If you have too much in your pack, consider the BLUNT Lite when it"s storming outside. The lightweight and agile design make it the perfect shield from downpour, especially if you"re camping, hiking, or simply need to grab an umbrella and go. The patented RTS design stretches the canopy as tautly as possible, preventing BLUNT umbrellas from turning inside out at a wind"s breath. With their sleek design, these umbrellas are the ultimate defense against the elements. Diameter - 41" Length - 31" (folded length) Weight - 1 lb Patented BLUNT Tips and Radial Tensioning System protects against heavy downpour and winds up to 70 MPH The RADIAL TENSIONING SYSTEM (RTS) redirects, transfers and distributes the effort used in opening the umbrella throughout the entire canopy surface. The RTS creates a strong, aerodynamic umbrella with no sharp points - the Blunt umbrella. A Blunt is opened by sliding the advanced Push/Pull runner upwards. This action is similar to a conventional umbrella. The Blunt differs by creating optimum tension in its canopy in a revolutionary new way. As the Blunt canopy unfurls the additional DOUBLE STRUTS redirect the user"s effort into the specially designed FLOATING RIBS. These ribs are telescopic, and reach out like fingers stretching into a glove. They transfer the opening force into the patented BLUNT TIPS on the end of each rib. The tips then open like miniature umbrellas in their specially designed pockets, evenly distributing the tension right to the edge, where it is most needed.
