Breathable Comfort Fit
Knot Theory rings feature a comfort fit design, to enhance comfort and improve air flow. The slight curve on the inside of your ring will help your finger stay fresh and dry so you can wear your ring comfortably 24/7. As an added bonus, it also helps prevent finger muffin top!
Other brands use grooves on the inside of the ring to boost air flow, but these grooves can trap moisture become sweat gutters.
Knot Theory's smooth inner ring surface is not only extremely comfortable and breathable, it also lends opportunity for custom engraving on the inside of your ring.
Free of Metals & Allergens
We make our rings as safe as possible, free of allergens and toxins.
If you are allergic to any metals such as nickel or copper, you can safely wear our rings. Knot Theory rings are made with metal-free and hypoallergenic pigments.
Silicone is a very safe material, but we took it one step further and only use food-grade silicone. The end product is a hypoallergenic high quality silicone ring that is durable and safe.
360º Inside & Outside Engraving
We spent a year developing the tools needed to engrave 360 degrees panoramically on the inside and outside of each ring.
We weren't the first to offer silicone ring engraving, but we are the best. We use the best laser engraving machines and the best tools which we have designed ourselves.
Whether your message is sincere or naughty, short & sweet or a full sentence, we got you.
