MY-CASE Silicone Watch Strap: 20mm width compatibility
Garmin's stock bands are functional, but this silicone replacement strap is where comfort meets customization. Designed specifically for models like the Vivoactive 3, Forerunner 245, and their kin, it slots in with a standard 20mm width—no guesswork, just a snug fit.
Made from soft, flexible silicone, it's the kind of band you forget you're wearing. All-day comfort? Check. Durability for the long haul? Absolutely. It's sweat-resistant and a breeze to clean, making it a no-brainer for workouts, runs, or even a dip in the pool.
Why swap it out? This strap ditches the itch. Hypoallergenic and gentle on skin, it reduces irritation while the secure clasp keeps your watch locked in during even the most frantic activities. Whether you're chasing personal bests or just want a sleeker look, it's a smart upgrade that blends practicality with a touch of style.

I just got this strap, and my first impression is really positive. It was easy to assemble and swap out from the original band. As someone who's into fitness and health, this has been a smart upgrade—it's durable and hypoallergenic, which reduces irritation I used to have. It's practical for runs and even handles water well, blending style with functionality. I'd definitely recommend it to others looking for a comfortable and reliable option. 😊
- Pros: The strap is extremely comfortable and feels soft against my skin all day, making it easy to forget I'm wearing it. It fits perfectly without any hassle, and I appreciate that it's resistant to sweat and easy to clean, which is great for my active lifestyle. The clasp is secure, so I never worry about it coming loose during workouts.
- Cons: From what I feel, there aren't any major downsides, but it might not suit everyone's style preferences, though that's a minor thing.
