"I love my new ring. It's much more comfortable than my previous titanium one. It did stretch ever so slightly which made it a better fit too."
Built to break safely.
Medical-grade silicone — engineered for the worksite, the gym, the rope-pull, the rock face. Non-conductive. Designed to release under tension before your finger does.
Almost weightless
You'll forget you're wearing it. Made from medical-grade flexible silicone that conforms to your finger and stays comfortable for 12-hour shifts.
Ring-avulsion safe
Engineered to tear at roughly 25kg of pull-force — well below what it takes to degglove a finger. Tradies, electricians, climbers, lifters: this is the ring you wear when the metal one comes off. Non-conductive, too.
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 Cosmoid Navy chain-patterned silicone ring features a distinctive interlocking chain texture on the outer surface, a bold, mechanical design built for active men. Made from premium medical-grade silicone, it is sweat-proof, waterproof, and non-conductive in a deep navy tone. The chain pattern adds visual depth and tactile grip while remaining lightweight and comfortable. Silicone rings break away under extreme pressure, protecting your finger from ring avulsion injuries during gym sessions, sport, or trades work. A ring with presence for the man who earns it.
