Powered by SWITCH patented magnetic interchange lens system—high-energy magnets embedded in the lenses and frame that let you swap lenses quickly and easily as light conditions and activities change. Ultra-light ArmourFusion® frames built from a combination of titanium and Grilamid® for maximum impact resistance. ArmourSight® lenses deliver up to 20% enhanced vision edge to edge, and are up to 10X stronger than ordinary polycarbonate lenses for ultimate durability and performance. Two sets of lenses included: Highly scratch-resistant Game Day Multiflection™ lenses to deliver superior visual contrast and object illumination & Crimson lenses to heighten visual acuity and enhance color, delivering a brighter field of vision especially in lower light conditions. 3-point grip and soft, adjustable nosepad and temples ensure a comfortable, secure fit. Cap gripper delivers a secure, slip-free fit when worn upside down on your hat. Advanced cushion hinge absorbs shock so you can keep moving without distraction. Airflow technology directs air through the lens to keep you cooler. All Under Armour® Performance Eyewear lenses block 100% of UVA, UVB, and UVC rays. Imported.
