Delicate insulin pumps and water don’t often mix well. This case will let you bathe, shower or paddle with total peace of mind.

Like most of our cases it’ll float if you drop it in the drink

But can I swim with it?
Although it’s not designated as Submersible we have had reports from many, many users that in practice they or their children have enjoyed swimming with our cases with no problem whatsoever (the vast majority of our customers have bought the case for their children). We are talking here about splashing around in the pool or the sea, but we are NOT talking about endurance/long-distance swimming. Our testing shows that the TC clamp will let a tiny amount of water in after a period of total immersion. So the best advice we can give is to wear it in the small of your back if you’re swimming on your front, and on your tummy if you’re swimming on your back, so that it spends as little time submerged as possible.
