These Voile Straps are made of tough stretch polyurethane, with a UV-resistant additive to increase their lifespan. Their heat-treated aluminum buckle features a slim profile for packing efficiency and extra durability. Few things in life are as reliable as the original Voile Strap. Over the last 30 years they have become the ultimate alternative to duct tape, nylon straps, and bungee cords. On the job, in the outdoors, and everywhere in between: they are the definitive way to secure, bundle, and repair almost anything on the go.
