Meet the Ripcord Retainer-the perfect fusion of brains and brawn. This retainer offers unparalleled functionality thanks to its harpoon system, which allows for swapping between two sets of interchangeable silicone ends, to adapt to countless eyewear styles. From wire-framed aviators to the thickest, chunkiest polycarbonate frames, the Ripcord plays nice with just about any pair of glasses you can throw at it. Crafted in the USA from durable 3mm nylon rope, and with extra-grippy silicone ends that will not stretch out or lose their shape over time, this retainer delivers the durability, versatility, and dependability to level up any adventure.
