Soften your shadows without losing any details Center weighted providing balance and ease of use Fits most standard bounce flashes Approximate light loss: 1-1/4 stops Folds flat to 8&#034; x 9&#034; The patented marriage of neoprene and Velcro loop results in a strap that applies a constant 3 pound tension to the flash with a non-skid surface The rugged UltraStrap attaches to most flashes in seconds to provide a secure flash attachment point Perfectly temporary yet secure enough to hold your most precious attachments Fits most standard bounce flashes Dimensions: 1&#034; x 11&#034;
