Full Road Versatility with Dynamic Conversion The Birdz Eyewear Phoenix Kit is the best adaptable eyewear for cyclists in ever-changing road conditions. This professional set lets you swiftly convert between attractive riding glasses and safe high-speed goggles. Remove the sunglass arms and connect the 25mm adjustable elastic strap for a secure fit. This secures the glasses even at high speeds. No matter your riding style, the Phoenix can handle tight city corners or the open highway. Three non-fogging lenses for all-weather vision Never ride dependent on weather or time. This kit includes three break-resistant polycarbonate glasses: Smoke Mirrored to reduce sunlight glare, Yellow to increase contrast on cloudy days, and Clear for the finest night ride view. The Phoenix package treats all six lenses with an anti-fog coating and 100% UV400 protection, unlike other brands. This blocks UVA and UVB radiation and moisture from impairing vision. Professional comfort and tactical durability A high-quality matte black frame with two layers of soft, airy foam padding makes the Phoenix durable for "use and abuse." This unique foam seals out wind, dust, sand, and other eye-irritating material. Since the plastic is light, you can wear them all day without worrying about impact. The Birdz zip-up belt case holds the entire system, including the goggle strap and extra lenses. This keeps your gear organized and protected when not riding.
