From full frame to half frame in seconds. In the blink of a nosepad. And swap the mirrored lenses for amber (bad light) or clear (drookit days). All of them’ll push water away when it’s wet. Comes with a hard case and protective sleeve. To keep safe from knocks and smashes. The Murphy’s law sort. Lightweight TR90 frame and rubber tips. And stiff polycarbonate lenses. 100% UV protection to EN ISO 12312–1:2013.
