FAQ
Is this strap waterproof for swimming?
Yes, the Silicone Racing Strap for Fitbit Charge 3 / 4 is completely waterproof and shower-safe. It does not absorb water, so it dries almost instantly after you leave the pool or shower. This makes it a great choice for triathletes and swimmers.
Will this fit the newer Fitbit Charge 5 or 6?
No, this specific strap is designed only for the Fitbit Charge 3 and Charge 4 models. The connector pins on the Charge 5 and 6 use a different mechanism and are not compatible with this racing strap. Please check your model before ordering.
How do I swap the bands?
The Silicone Racing Strap uses the standard Fitbit quick-release system. Simply press the latch on the underside of your tracker to slide the old band out and click the new racing strap into place. It takes less than ten seconds to swap styles.
Does the color fade over time?
The silicone is UV-resistant and color-fast. Unlike cheaper rubber alternatives, this material is designed to retain its vibrant hue even with daily exposure to sun, sweat, and chlorine. A quick rinse keeps the colors looking sharp for years.
