Can you swim with your Magic Band on?
Yes they are waterproof.
Yes I can, and I can swim without it on too. Sorry, couldn’t resist.
In fact, I recommend wearing them into the shower or pool. In warmer months (you know, March - October) they tend to accumulate sweat and channel it, so it kinda runs down one’s arm.
Ewwww. Maybe they need to be worn in the shower then.
