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.
Days warranty
Silicone doesn't last a lifetime and we won't pretend it does. 30-day replacement warranty on tears, splits, or manufacturing defects. After that, swap it for a fresh one — they're built to be replaceable.
