FAQ
Can I wear this band while swimming?
Yes, the silicone material is completely waterproof and non-absorbent. It is ideal for swimming in pools or salt water. We recommend rinsing the band with fresh water after swimming to remove any chlorine or salt residue that might sit against your skin.
Does the silicone cause skin irritation?
This band is made from BPA-free, hypoallergenic silicone. It is designed to be skin-friendly for long-term wear. If you have sensitive skin, we recommend cleaning the band regularly and ensuring your wrist is dry after exercise to prevent moisture from being trapped against the skin.
How do I clean the sports band?
Cleaning is simple. Use mild soap and lukewarm water to wipe down the strap. For tougher dirt or sunscreen buildup, a soft-bristled toothbrush can be used to gently scrub the surface. Pat it dry with a lint-free cloth or let it air dry before reattaching it.
Is the buckle adjustable?
The band features a classic watch buckle with multiple adjustment holes spaced closely together. This allows you to find a precise fit that is tight enough for accurate heart rate tracking but loose enough to remain comfortable during sleep or heavy activity.
