What it does
A men's silicone wedding band from ThunderFit, 8.5 mm wide and 2.5 mm thick, with grooves on the inside to let air reach the skin, sold singly or in multipacks.
- Inner grooves meant to let air circulate and reduce trapped moisture
- Soft, flexible band that can stretch over large knuckles
- Multipacks give spares or several colors
- ThunderFit's own store offers a free replacement if a ring does not fit
A budget silicone band for the gym, job site or travel, where a metal ring is a nuisance. It is soft and flexible and comes in multipacks, but silicone at this price can stretch over time, so plan on replacing it rather than wearing one for years.

Questions
Do ThunderFit silicone rings stretch?
They can. A comparison from a competing brand notes ThunderFit bands may loosen over time, which is common with soft silicone.
How do you pick a ThunderFit ring size?
ThunderFit sells rings in half size ranges and points buyers to its size chart. Measuring finger circumference in mm and matching it to the chart is the safest route.
What if the ring doesn't fit?
ThunderFit's own store says it will send a new ring free if the size is wrong. Amazon orders follow Amazon's return rules.
Are the grooves inside the ring noticeable?
They sit on the inner face only, so the outside looks like a plain band.
