There seem to be some consistent terms that Apple uses when naming watch bands. Keeping them in mind when you see posts about what bands someone has ordered helps keep me straight on what’s going on. Sport - elastomer or nylon, light weight and easily cleaned. Loop - No clasp mechanism. Solo - Stretch to fit. Needs precise sizing. There are more terms, but they are either obvious or only used on one band, so I’m not bothering with them. Nike bands are variations of color and design of the sport bands.
