The Most Comfortable Sports Frame
Our hypoallergenic adjustable nosepad is mounted with titanium screws and a titanium core to produce the lightest, most comfortable sports frame. We recommend visiting a preferred optician to ensure a durable and comfortable fit.

Each frame is accompanied with an Ultrasuede® pouch, serving as both a storage solution and a lens-cleaning accessory. Ultrasuede® is a soft material with a luxurious texture incorporating 30% recycled plant-based fibers, utilizing advanced fiber technology pioneered by Japan’s Toray Industries, Inc.

D+ Onyx Mirror

D+ Onyx Mirror was developed for physical pursuits requiring maximum sun protection. The mirror coating facilitates additional infrared screening. The lens offers 100% UVA/B protection while transmitting 16.19% of visible light and 15.99% of blue light. Athletes often forget sunglasses are a medical device. Unlike our skin, our eyes do not contain melanin. This means each time we expose them to sunlight they become more sensitive.

Sports Lens of the Future
D+ lens technology is constructed from a proprietary form of polycarbonate, which is shatterproof. The lens interior features an anti-reflective application for holistic eye protection. The lens is finished with our oleophobic treatment making it water and oil repellent.

Titanium Grade 2
Our frames are crafted with grade 2 titanium, providing strength while retaining flexibility. Grade 2 ensures durability along with a high level of corrosion resistance, making it a material widely utilized in aerospace applications.
