What Our Gearhead(R) Experts Are Saying:"I wore the Active Sci-Fi Polarized Sunglasses through a full day of trail running with the side shields attached, and they never budged, even sweating through the last few miles. The rubberized nose pads made all the difference on the steep climbs."Some sunglasses are made to look good sitting still, and some are made to move, and the Blenders Active Sci-Fi Polarized Sunglasses are unmistakably the second kind. We love how the attachable side shields let you switch up your setup on the fly, whether you're blocking extra glare on a long run or popping them off for a wider field of view on the drive home. Rubberized nose pads and temple tips keep everything locked in through sweat, motion, and whatever else the day throws at you, while the polarized PureBlend lens holds up to scratches and stays clear no matter how hard you're pushing. It's a bold, rugged build made for people who actually use their gear.
