    Very good. I've had to exchange rings a couple of times due to sizes. They were super efficient with the exchanges.

    Won’t last forever, but great warranty

    My first ring last almost 2 years, not bad for $30 and lots of active use wear and tear. But a simple email exchange with a picture of it tearing quickly got me a replacement ring for the cost of shipping - Groove will keep my business with these kinds of experiences!

    I love my groove ring so soft and flexible. I own both the groove and qalo rings, but I prefer my groove the most. I probably couldn’t even find my qalo if I tried.

    Best ring ever!

    I bought this ring because I don't like wearing my wedding rings when doing outdoor activities. I leave my other jewelry on all the time -until it wears out or falls off. I bought the size 8 and it was too big (my fault) so I wear it on my middle finger and bought a size 6 for my ring finger at Gravity Sports in McCall. One black, the other white. I love them both and I'll probably wear them until I die:). They paddle boarded, mtn biked, cleared trails, and road biked with me and were very comfortable in all activities.

     Groove Thin Specs:

  • Groove Ring is the first breathable active silicone ring. It is tough, low profile, and comes with an UNLIMITED Lifetime Warranty. It is the last ring you will ever buy!  Groove is for the athlete, the adventurer, the professional, the trend setter.  It begs to be worn, shown and tested everyday no matter what the circumstance.

    Groove "Thin" is designed for the person looking for a little less bulk but the same great function.  Like the Groove Original, the Thin is a unisex ring that looks great no matter who is wearing it.  Groove is the only active ring on the market to offer breathability.  Because of this, Groove is to be worn snuggly on your finger which keeps your ring from catching and grabbing on things in your environment.  

    Made from 80 durometer medical grade silicone, Groove is the first and only active ring to be liquid poured. This means fine detail and perfect design with little to no mold marks or flaws.  Groove silicone is resistant to most common chemicals including gasoline, oil, diesel, & household cleaning products.  Groove is also non porous, non conductive, heat resistant, and hypoallergenic.

    Groove is two rings in one.  We first began with the inner ring.  Firmer and full of infinity grooves that allow the ring to breathe.  The inner ring also features an inverse arch know as a comfort fit that lessens the contact with your skin.
