When you buy your Apple Watch, you get to choose which band you get. Skip the rubber bands, which are made from fluoroelastomer. While the company committed[1] to removing PFAS from its products in 2022, we have not gotten confirmation that Apple’s products are PFAS-free.
I find the textile and metal bands to be much more attractive and comfortable than fluoroelastomer bands, which tend to trap sweat and irritate my skin. My favorite of the Apple bands you can choose at checkout this year is the Nike nylon woven Sport Loop. It’s soft, breathable, soaks up sweat, and is infinitely adjustable if your wrists swell when you run. It’s made from recycled polyester, spandex, and nylon, and the yarn is reflective if you’re running at night. It comes in five colors and three sizes, so it’s compatible with the 40-, 44-, and 46-mm watch sizes.
