Materials & Build
We use a flexible, skin-safe silicone that measures approximately 2.2mm in thickness. The surface features a geometric diamond pattern embedded with subtle reflective elements that catch the light without feeling rough. The hardware is made from polished 316L stainless steel, ensuring the buckle resists rust even if you wear it in the pool or shower daily. The material is UV-stable, meaning the vibrant colors will not fade or yellow after exposure to the sun during outdoor runs.

Sizing & Fit
This strap follows the standard Fitbit sizing conventions to ensure a perfect fit for everyone. The small length fits wrists between 140mm and 180mm (5.5" to 7.1"). The large length fits wrists between 180mm and 220mm (7.1" to 8.7"). The band width is specifically tapered to match the 22mm lugs of the Charge series for a seamless, integrated look. Because the silicone is flexible, it stretches slightly to move with your muscles during exercise.

FAQ
Can I swim with this strap?
Yes, the silicone material is completely waterproof and the hardware is rust-resistant. It is perfect for laps in the pool, ocean swimming, or simply wearing in the shower. Just rinse it with fresh water afterward to remove chlorine or salt.
How do I clean the diamond texture?
The textured surface is easy to maintain. Simply use mild soap and warm water. If dirt gets trapped in the diamond grooves, a soft toothbrush can help clear it out in seconds, keeping the strap looking brand new.
Will the color fade or peel over time?
No, the color is molded directly into the silicone rather than painted on the surface. This ensures the shade stays vibrant and will not peel, crack, or fade even with daily wear and exposure to sweat.
Is it easy to install on my Fitbit?
Installation is instant. The strap uses the standard Fitbit Charge 3/4 clicking mechanism. You simply slide your old band out and click this one in. No tools or extra pins are required for the swap.
