We've procured a premium selection of frames to ensure you're flexing fashion and function, on or off the courts. All lenses are TAC (Tri Acetate Cellulose) Polarized for superior clarity. This means that there are 7 layers that make up our lenses. The first is a polarizing layer that provides more than 100% polarization and absorbs glare. The second and third layers allow durability to resist harsh environments. The fourth and fifth provide UV protection. The last two are shock proof layers that increase impact and scratch resistance.
