Original owner of sunglasses purchased over 10 years ago, rarely used. Evolve Aura model with brown techlite lenses, lightly gradient ( not polarized). Sturdy but classic style frame with rubberized nosepieces, limited lifetime warranty for those not familiar with Smith Optics. Cleaning out closet in hopes someone will find these and avoid the nosebleed prices of new Smith Optic sunglasses (tariffs?).
