The CoupleR is BlackRapid's simplest solution to carrying two cameras. By coupling any two R-Straps in the back, and wearing them like a backpack, your cameras will hang vertically at your sides. You'll feel free and secure while having both cameras quickly accessible. The CoupleR is made from the same bomb-proof webbing used on the R-Straps, with the addition of high strength elastic for automatic sizing. Simply snap one or more CoupleRs to the back portion of two R-Straps, and adjust their height for comfort. Presto!, two cameras at your beck and call.
