The Bliz Speed is the performance glass for extra small faces. Kids or small faced adults will appreciate its soft and infinitely adjustable nosepieces and its friction rubber temples that allow for the perfect small face fit. Speed weighs only 21 grams. Adjust the speed close to your face for high speed sports like cycling or slightly farther off the face for medium speed sport like running or cross country skiing. Each speed kit comes with one lens set and a soft microfiber case.
