Water Resistance:
Ace is rain, sweat and shower proof (IPX7), but not swimproof. Make sure that you rinse and dry Ace after kids shower in it - it;s best for their skin if the band stays dry and clean.
Care:
If your child gets Ace wet or sweats in it, remove and completely dry the band before they put it back on. Make sure kids take the band off every now and then and regularly clean the band and the wrist area around it with water. Do NOT use hand soap, body soap, dish soap, hand sanitisers, cleaning wipes or household cleaners, which could get trapped beneath the band and irritate skin. Children with eczema or a skin condition should talk to a doctor before wearing.
