Reducing glare bouncing off high-reflectivity surfaces, such as blinding snow-capped peaks and glistening ocean bays, the Tifosi Optics Women's Alpe 2. 0 Polarized Sunglasses offer a crystal-clear window to the outside world. The polarized polycarbonate lens not only ensures 100% UVA and UVB protection on the brightest days, but it also provides the extra protection of a shatterproof lens when you're exercising outside. Additionally, hydrophilic rubber nose and ear pads ensure a secure fit, even during sweaty exercise sessions. Made for fast-paced outdoor activities, the Alpe 2. 0 Polarized is extremely tough with a virtually bombproof Grilamid TR-90 frame. Adjustable ear pads tailor the fit to your liking, working best with small-to-medium faces. Moreover, it's RX-compatible with Tifosi's DirectFit technology. There's also an included hard case for safe storage and convenient travel.
