The Spigen DuraPro Armor strap is made of modern materials that combine durability and style to create a great addition to your smartwatch. Thanks to the use of two materials, nylon and TPU, they create a strap with two layers, ensuring not only durability, but also comfort during use. The patterned structure of the strap emphasizes the modern design, but also guarantees excellent breathability even in intense situations. The metal connectors perfectly complement the whole.
