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.

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 Hollow Square Blue silicone ring features a squared cross-section with hollow channels in a clean, bold blue tone. Made from medical-grade silicone, it is sweat-resistant, waterproof, and non-conductive for safe use in any environment. The angular squared exterior delivers a strong, distinctive look while hollow construction keeps the ring light and comfortable. Silicone rings are designed to break away under extreme pressure, eliminating the ring avulsion risk associated with metal bands. A modern, innovative ring for active men who want something different.
