The Fitbit Ace accessory band is made of a flexible, durable elastomer material similar to that used in many sports watches and includes an aluminum buckle. This band is rain, sweat and shower proof (IPX7), but not swim proof. Make sure to rinse and dry Ace classic bands after kids shower in it—it’s best for their skin if the band stays dry and clean.
