The FKT High Lonesome sunglasses put a modern twist on the classic alpine design. Circular frames lend the shades their unique style, while shatterproof polycarbonate lenses shield your eyes from the sun with 100% UVA/UVB protection. FKT’s Trail Vision technology enhances optics and depth perception, while filtering blue light, to give you uncompromised vision in variable light conditions. FKT built these sunglasses from a lightweight recycled nylon blend frame and gave them adjustable temple tips, so you can dial in the fit for a no-slip, no-bounce ride. Named for the popular trail outside Boulder, Colorado, the FKT High Lonesome sunglasses are purpose-built to help you conquer your next challenge. Why aren’t FKT’s lenses polarized? Because polarization isn’t what a trail athlete needs. Polarization cuts glare if you’re on the water or snow, but it can cause depth perception issues if you’re running on a trail with variable light conditions.
