Let's Get Dressed (and Undressed)
When designing the OSleeve, we worked to make it easy to install and remove from your smart ring. That's especially important if you're only wanting to use your OSleeve when working out or doing hand-intensive activity that could easily damage your ring (hint: metal against metal never ends well for a smart ring).
And guess what the best part is?
If you already know your smart ring size, selecting an OSleeve size is easy.
We've carefully selected our materials to be able to safely stretch up to 3 ring sizes without tearing or sacrificing function. So, within the sizing drop down, you'll see your smart ring brand and their specific sizing brackets.
Just select the right brand and your size and BOOM! You've got OSleeve magic in your cart.
Installation and Care Instructions (with FAQ)
How to Keep Your OSleeve Looking Good for Longer
- If your OSleeve gets dirty or exposed to dye or transferrable color, please put it into clean water ASAP. Use your fingers to rub the surface of the OSleeve with colorless soap & dry with a clean cloth.
- Every 3-5 days, take your OSleeve off your smart ring & wipe down with a dry, clean cloth. This is especially true if you shower or wash your hands with the OSleeve installed as it will trap water.
- When not on your smart ring, please store somewhere clean & dry. Our OSleeve will pick up dust/dirt when they're thrown into your gym or handbag.
- Take your OSleeve off during the application of facial/body lotions & oils. You can put it back on after they've been applied. What we do, is just take off both the smart ring and OSleeve as a paired unit, put on our lotions/oils, then put the smart ring/OSleeve unit back on.
- If you'd like an alternate option to use when you're working with things that would affect the clarity or aesthetic of your OSleeve, you might like to purchase a fully opaque color such as black.
- If your OSleeve no longer fits your smart ring snugly, please email us.
