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.
