The ERGO FIT® Collection

Where complex curves meet simple design. Two designs to capture the aesthetics of The Traditional Nanaco Men and The Modern Nanaco Men.

In our first collection, the goal was to incorporate our guiding principles of design to come up with a solution where complex interior curves meet simple lines to deliver a design that is honest and true to the function of our rings.

  • 1. KNUCKLE SIZE

    Men have larger knuckles than women. The size difference between the finger and the knuckle can vary anywhere from a half size to three whole sizes.

  • 2. BAND'S WIDTH

    Men typically wear bands that are thicker in width than women. The wider the band, the smaller it feels on your finger.

  • 3. INTERIOR SHAPE

    The available ring shapes of rings do not equal in size. A comfort fit ring may feel, on average, one whole size larger than a standard fit ring.

  • 4. BODY TEMPERATURE

    Changes in body temperature can cause fingers to shrink and expand.
