Can I wear a Reparel Sleeve while Scuba Diving

It is not recommended.

I would not recommend wearing a Reparel Sleeve while scuba diving. The dynamics of scuba diving, including water pressure and movement, could affect the fit of the sleeve, causing it to potentially shift or not stay in place properly. This could lead to discomfort or compromise its effectiveness. It's best to opt for appropriate diving gear designed specifically for underwater activities to ensure safety and comfort.
