Alpina Penken - Without a frame, without borders. The Penken is the right goggle for you if you want to underline your individual freeskiing style with the right glasses. The cylindrical and frameless shape, heavily mirrored lenses and a size that fits everyone make the Penken everyone's darling. The Airframe Venting System prevents the pane from fogging up. That way you always have a clear view of the essentials, the next jump, a new trick or the umbrella bar. Choosing Penken means making the right style decisions. It doesn't matter which color combination you choose.
