Hi Tegan, swimming with the Fusion would cause moisture to develop inside the screen and eventually lead to a dead device. Essentially, we suggest limiting water exposure as much as possible, especially if it involves full submersion under water. The Fusion can handle sweat exposure and light water exposure (e.g. while washing your hands) without issue. Hope this helps!

I just purchased a Striiv Fusion and was wondering just how "water resistant" it is... I understand that you can take a shower/bath while wearing it but would swimming damage it?
