One is sweat, rain and splash proof. However, the device is not swim proof. With any clip-based wearable device, it’s best for your skin if the clip stays dry and clean.
You can clip One to a belt, pocket or bra. Always use the silicone holder when clipping it to a bra or waistband as the plastic One tracker is not meant to be worn in direct contact with the skin. Make sure the One display faces outward when clipped to your bra. Learn more
The One tracker is made of thermoplastic. The clip is made of silicone and metal.
