Is the OSleeve waterproof and water tight?Updated a year ago

The OSleeve itself is 100% waterproof. You can keep it installed on your smart ring while you shower or wash your hands.

However, because the OSleeve does not form a water barrier against your smart ring, you will find water gets trapped - most noticeable with the clear OSleeve. That means it isn't water tight. We recommend you remove the OSleeve and with a soft cloth or tissue, dry the inside of the OSleeve and smart ring before re-installing it.

Please note that normal hand hygiene and care apply here. It's never a good idea to have dampness under any ring (or jewelry in general) as that will harbor bacteria and other nasties. 

Dry your hands well and ensure you pay attention to underneath jewelry.
