Series 9 45mm with Sport Band (Green)

Yes, the Green Sport Band is made from a custom high-performance fluoroelastomer, which is highly durable and completely sweat-resistant. This makes it an incredibly natural fit for rigorous outdoor activities like hiking, running, or cycling trips. It is also water-resistant, meaning it can easily handle sweaty workouts or sudden rain showers without degrading.

Yes, Apple has maintained perfect backward compatibility, meaning any band designed for a 45mm Apple Watch will fit the Series 9 45mm model. You can easily swap out the Green Sport Band for an older Link Bracelet or Milanese Loop. The proprietary connector mechanism has remained unchanged since the introduction of the larger 45mm sizing.

While the fluoroelastomer material is safe for most users, tightly worn sport bands can trap moisture and cause skin irritation during intense sweating. To prevent this, Apple recommends rinsing the band with clean water after workouts and keeping the skin beneath it dry. If you have a known allergy to fluoroelastomer, you may want to look into the woven or leather strap alternatives.

The aluminum 45mm Series 9 case weighs just 32 grams, and the Sport Band adds a marginal amount of weight, keeping the watch incredibly lightweight on the wrist. This rugged but light profile makes it unnoticeable during long outdoor cycling or hiking trips. It is noticeably lighter than the stainless steel or titanium case variations.
