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.
