Features We test umbrella to breaking point and measure the force at the point they fail. This enables us to take a kaizen continual improvement approach. The Blunt Classic is our flagship design and has been tested up to 72 mph or Force 11 winds. All BLUNTTM umbrellas feature patented BLUNTTM Tips that form an integral part of their unique Radial Tensioning System (RTS). A system that redirects, transfers and distributes the effort used in opening the umbrella throughout entire canopy surface. Never fear about harming a passerby again. Ever had trouble with the wind throwing your canopy in all directions? Well not any more. The fully tensioned canopy creates an aerodynamic and robust structure, making BLUNTTM umbrellas the ultimate defense against the elements. Every single BLUNTTM umbrella has an independent 38 point check before it reaches you. This ensures we keep the high standard we set for all products carrying the BLUNTTM name.
