The Alpine Loop contains 43% recycled content by weight, and 100% of the manufacturing electricity is covered by clean energy. The rugged Alpine Loop is made from two textile layers woven together into one continuous piece without stitching. High-strength yarns reinforce the top loops, and the corrosion-resistant titanium G-hook slides easily into the loops for secure fit. | Apple Watch 49mm Alpine Loop - Black - Medium 145-190mm
