The robust Alpine Loop is made from two layers of fabric that are woven together into a continuous piece without seams. High-strength yarns reinforce the upper loops, and the corrosion-resistant titanium G-hook easily fits into the loops, ensuring a secure fit. This band is climate neutral. The Alpine Loop is composed of 43% recycled material, 100% of the electricity used in its production comes from clean energy, and at least 50% of all climate-neutral Apple Watch products are shipped without airplanes.
