"Goodr® Silverback Squat Mobility Sunglasses: The Goodr® Silverback Squat Mobility Sunglasses are unisex performance sunglasses built for active outdoor use, from lifting sessions to runs and high-action outdoor adventures. Weighing just 22 grams, the OG frame sits lightly on a normal face size without slipping or bouncing during movement. The grey frame with purple/teal lens gives these shades a distinctive look that holds up across a range of activities. For anyone who wants reliable sun protection without sacrificing style or stability, these sunglasses are a practical everyday accessory.The lenses stack five functional layers into a single lens construction: a scratch-resistant layer, an anti-corrosive layer, UV 400 protection, full polarization, and a gradient tint. Polarization reduces glare so that visual clarity stays consistent whether you're running roads, training outdoors, or spending time at elevation. The UV 400 protection layer blocks harmful ultraviolet rays across the full spectrum. At 42 mm lens height and 53 mm lens width, the lens dimensions deliver solid coverage without an oversized fit. The no-slip design means the frame stays in place through squats, sprints, and everything in between.Why Our Fit Experts Love It""I grabbed these for an outdoor workout that mixed lifting and a short run, and they didn't shift once.
