We like the Sunski Tera Polarized Sunglasses for their superior protection from the bright sun and reflective glares. Designed with alpine use in mind, the Tera features a dark, polarized lens that blocks 100% of UVA wavelengths, making these glasses great for high-mountain hikes or a day at the lake. Magnetic side shields provide added protection against glare and are easy to remove when the clouds start to add some coverage.
