"Ordered 2 rings and they arrived super quick and packaging was great. Have had no issues with the Black blue ring, however the 2nd silicone ring has already the colouring and only had it for 2 weeks. I will stick to Black from now on as they are very comfortable."
"Perfect ring for my partner to wear as a tradesman - looks great too"
"This ring is really cool. I like the design as it really stands out. I’ve had a lot of compliments. It fits nice and snug and doesn’t move around"
"Was unsure what to expect as was used to traditional metal rings and was pleasantly surprised. The ring came quickly and fits well, i dont notice it being on my finger and can carry out all daily tasks wirh it on. Would recommend to get."
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.

The details.
The Dynamite Black Silicone Ring with Blue Centreline is a bold, athletic band featuring a striking blue accent line running through a black outer band. Made from medical-grade silicone, it is sweat-resistant, waterproof, and non-conductive for safe use anywhere. The two-tone design delivers visual impact and a sports-inspired aesthetic that suits gym-goers, athletes, and active tradies. Silicone rings break away under extreme pressure, protecting against ring avulsion during physical work or sport. A confident ring for the active man who moves with intent.
