Alpine band in beige for 49 mm envelope - size L - natural titanium elementsThe durable Alpine armband was created by weaving together two layers of fabric into a seamless unit. Ultrathin fibers reinforce the top loops. And a corrosion-resistant titanium g-shaped buckle slides smoothly into the loops to create a secure closure.This headband is carbon neutral. The Alpine armband contains 43% recycled materials (measured by weight), and the electricity used in its production was sourced 100% from clean sources. In addition, at least 50% of carbon-neutral Apple Watch products are transported without the use of airplanes.
