BEST FOR: HIKING
Glass lenses are less impact-resistant than polycarbonate but have better acuity, a fine trade-off for lower-intensity activities like hiking. The Tenet’s glass is ground thinner to save ounces, and its polarchromic Ignitor lenses – which adjust tint to brightness so you don’t need a sheaf of interchangeable ones – offer an impressive range of tints that helped us navigate bumps and turns on both sunlit and shady trails.
