Materials & Build
We build this strap from 100% hypoallergenic silicone rubber. The material is 2.5mm thick for long-term durability but remains flexible enough to wrap around your wrist without a break-in period. It uses a stainless steel buckle that resists corrosion from sweat or saltwater. The connector is molded precisely to fit the Fitbit Charge 3 and 4 housing, ensuring a snug fit without any gaps or rattling. The surface is finished with a matte coating that repels dust and lint.

FAQ
Can I swim with this strap?
Yes, the silicone is fully waterproof and shower-safe. It does not absorb moisture like nylon or leather. We recommend you rinse it with fresh water after swimming in chlorine or salt water to maintain the finish and remove any chemical residue.
Is it easy to swap colors?
The strap uses the standard Fitbit click system. You can swap colors in under ten seconds without using any tools. Simply press the release button on the tracker, slide the old band out, and click the new Breathable Silicone Sport Strap into place.
Will it irritate my skin?
We use medical-grade silicone that is BPA-free and hypoallergenic. The unique perforated design also reduces the amount of moisture trapped against your skin. This airflow helps prevent the common rashes associated with solid rubber bands during heavy exercise.
How do I clean the band?
Maintenance is simple. Use mild soap and warm water to wash away dirt or sweat. For stubborn grime in the ventilation holes, a soft toothbrush works well. Because it is silicone, it dries almost instantly with a quick towel pat.
Does it fit the Charge 5 or 6?
No, this specific connector only works with the Charge 3 and Charge 4 series. Newer Fitbit models use a different attachment mechanism. Please check your model number before ordering to ensure a perfect fit for your device.
