"Really comfortable light weight ring. I wear it to the gym everyday and forget it’s even there!!!"
"It fit perfectly and is very handy to be able to wear at all times without worrying about wear and tear"
Flexible for everyday wear.
Flexible silicone offers a lightweight alternative to a metal band. A ring is not protective equipment; remove jewellery whenever your activity or workplace requires it.
Almost weightless
Flexible silicone has a soft, lightweight feel. Choose a comfortable fit and remove the ring if you notice irritation.
Choose when to wear it
Silicone rings can catch or tear. They do not guarantee protection from injury. Follow workplace, machinery and activity rules, including removing all rings where required.

Not sure of your size?
Silicone is flexible — but the right size makes a real difference for comfort. Three ways to check before you order.
The details.
The Twin Groove Black Urban silicone ring is a flat-profile band with two clean parallel grooves running around the outer edge, adding structure and a mechanical look to a performance-grade active ring. Made from premium medical-grade silicone, it is sweat-proof, waterproof, and non-conductive for any environment. The groove detailing gives grip and visual depth while the flat profile sits comfortably under gloves and gear. Silicone rings break away under extreme pressure, protecting your finger from serious injury. A clean, engineered ring for active men who want detail and function.
