These Voile Straps are made of tough stretch polyurethane, with a UV-resistant additive to increase their lifespan. Their Super Tough nylon buckle is non-marring, non-conductive, and non-reflective. Voile Straps have become synonymous with utility. They are like a business card, but better. They are long lasting, infinitely useful, and prized by those who own a hand-full of them.
