Oakley SI Tightrope

Oakley's SI Tightrope sunglasses blend style, comfort and practicality to produce functional, ultra-lightweight eyewear that can be worn in any lighting situation. The ergonomic, hi-modulus C-5 frame is built to sit securely on the ears via a three-point fit, that also keeps the lenses in perfect optical alignment. The stems feature patented hydrophilic Unobtainium earsocks to ensure comfort and security. They are also thin enough for use with a helmet. The Plutonite lenses are designed with XYZ Optics to maximize clarity and protect eyes from harmful UVA, UVB, UVC and blue light up to 400 nanometers. These glasses may sport a sleek, low-key look, but they are engineered for comfort, sun protection and functionality.

      This is not sold by Oakley anymore so it was great to still find this great style of glasses.

    • Functional but fragile
      Reviewer: Prior Service

      I've owned these sunglasses about 2 weeks now; they were purchased to replace a ~10 yr old pair of SI wireframe ballistic sunglasses (discontinued). Those glasses were tough as nails, but this new pair seems more fragile. They are much lighter (the first thing you noticed about the old ballistic glasses was how weighty they were) and I suspect they will not be as durable over the long term. That said, these are about half the price as the old ones. The arms, especially around the ear, have been slightly redesigned to be more comfortable, and they likely won't scratch the inside of the lenses as much as the old model did over time. Apart from that, they are performing as expected.

      This is my second pair of Oakley's Tightrope sun glasses I've owned and they are the best on the market. I love them and are extremely comfortable. These are great.

      When the glasse are closed, the ear pieces rest against the lenses & scratch them
