4Play Lens System
With the 4Play system, a lens change has never been made more spontaneous. 2 lens release buttons on the brow line and 2 buttons on the bottom of the frame remove the lens. To insert, line up the lens on the goggle mask and lovingly thrust the lens into place. All this can be performed wherever and whenever the conditions (or your mood) changes, with gloves on (for your protection) or off, all you have to do is lower your inhibitions and initiate 4Play.
