We're thrilled to release our first ever sunglasses! After researching, and wear testing, and determining what was needed most, we landed on a short list of must haves: first and foremost, ultra-lightweight and an ergonomic shape for a stay-put fit. No more sliding down your nose when the run heats up. Second, flexibility of materials, including arms that bend but don't break. Third, polarized and scratch-resistant lenses, for crisp vision in any conditions. Already tested on 6, 10, and 18 mile runs, consider these your new eagle eyes! Introducing the runglasses!
