FAQ
Is this strap waterproof?
Yes, the silicone material is completely waterproof and shower-safe. You can wear it while swimming, diving, or in the rain without damaging the band. We recommend rinsing it with fresh water after salt or chlorine exposure to maintain the finish.
How do I clean the silicone?
Cleaning is simple. Just wipe the strap with a damp cloth or rinse it under warm water with mild soap. This removes salt, sweat, and oils to keep the band looking new and prevent any skin irritation from buildup.
Does it come with the Fitbit tracker?
No, this product includes the silicone replacement strap only. The Fitbit Charge 3 or 4 tracker device is not included with your purchase. This is an accessory designed to fit your existing hardware.
Is it easy to install?
Yes, the strap features the standard Fitbit Charge connector. It snaps into the tracker lugs in seconds. You do not need any special tools or hardware to swap your old band for this new one.
Will the color fade?
Our silicone is UV-resistant and color-fast. The vibrant shades are designed to stay bright and consistent even with regular exposure to sunlight, sweat, and water. It will not peel or lose its pigment over time.
