Ortovox 140 Cool Beanie - For cool walls on hot summer days. The 140 Cool Beanie ensures comfortable temperatures when things get strenuous in alpine terrain. The 140 Cool line combines fine merino wool with the cellulose fiber Tencel Lyocell and impresses with its temperature and moisture regulating properties. The light hat dries quickly and is particularly comfortable to wear, but still has the necessary resistance for use in alpine terrain.
