The Apple Watch Sport Loop band is woven from nylon thread to create a hook-and-loop closure. They were available for the 38/40mm and 42/44mm Apple Watch models, and were offered in sizes to fit 130–190mm wrists.
The Apple Watch Sport Loop band has been available in several styles, including (PRODUCT)RED, Spicy Orange, Nectarine, Electric Pink, Hibiscus, Hot Pink, Pink Sand, Flash Light, Flash, Marine Green, Tahoe Blue, Cape Cod Blue, Midnight Blue, Indigo, Dark Olive, Storm Gray, Black, and Seashell.
Apple described the Apple Watch Sport Loop band:
“Soft, breathable, and lightweight, the Sport Loop features a hook-and-loop fastener for quick and easy adjustment. The double-layer nylon weave has dense loops on the skin side that provide soft cushioning while allowing moisture to escape. On the reverse side, the attachment loops are securely anchored for superior durability.”
This Cape Cod Blue Sport Loop has an overall bright bright blue appearance, but is comprised of a bright blue base color with light blue and dark blue accents. This example also includes unboxing photos, and the internal packaging includes installation instructions.
The Apple Watch Leather Loop band is comprised of leather-wrapped magnets. The band is sold in two sizes, Medium for 150–185 mm wrists and Large for 180–210 mm wrists. They are available for both the 38/40 mm and 42/44 mm Apple Watch models.
The Leather Loop band was among Apple’s original band designs in 2015 and has been available in several colors, including Stone, Light Brown, Saddle Brown, Forest Green, Cosmos Blue, Cape Cod Blue, Bright Blue, Midnight Blue, Black, Charcoal Gray, Storm Gray, Smoke Gray, White, and Meyer Lemon.
Apple describes the Apple Watch Leather Loop band:
“The Venezia leather for this band is handcrafted in Arzignano, Italy. With an artisan heritage spanning five generations, the tannery has a history of partnership with some of the most prestigious names in fashion. A delicate milling and tumbling process enhances the beautiful pebbled texture. And magnets concealed within the soft, quilted leather allow you to simply wrap it around your wrist for a precise fit and a trim look.”
This Cape Cod Blue band has been among the more unusual colors offered by Apple, and I pair mine with with Stainless Steel, Aluminum, and Space Gray Apple Watch models. I like this style because it uses no mechanical fasteners that might potentially scratch a surface.
