Now using our locking speed buckle for quick, non-slip adjustment the Safe Tech Waldo harness is the world's most comfortable big wall harness. This is also the harness of choice for route setters, and anyone spending long days hanging in a harness. Our patented, adjustable-rise 3D system creates the best-fitting harness in the world, and 1/2" (12mm) thick slabs of foam contour around waist and legs for ultimate comfort. Monstrous components (5-5/8" (143mm) waist belt and 5" (127mm) leg loops) spread the load. Super-durable, closed-cell polyethylene foam with fleece lining also contributes to maximum comfort. The Waldo has diamond pattern body fabric and drop seat rear elastics, as well as dual front belay loops to minimize gear clutter. There are six gear loops on the medium and large, five on the small.
