The Head RADAR 5K POLA men’s ski helmet with an integrated 5K polarized visor provides the clearest possible vision without any disruptive elements. It fits perfectly on the head, has excellent ventilation controlled by a single slide to the closed/open position, a button at the back for a perfect fit and a magnetic safety strap under the chin. The visor is attached to the rubber cords and either fits perfectly into the helmet, or you simply open and snap it onto the brim of the helmet.
