Keep a sharp vision on the slopes in all circumstances thanks to the Smith 4D Mag S. These ski goggles feature a magnetic interchangeable lens system for quick and easy lens swaps. They feature the BirdsEye Vision technology that provides a wider field of vision and a clear view of your line and the skiers around you. The ChromaPop lens ensures better contrast and improves the natural colours to enhance the details. For more sharpness, it features the TLT technology. The lens benefits from a 5X anti-fogging coating and an anti-scratch coating to retain maximum optical quality.  Beyond visual comfort, the goggles are also pleasant to wear. Designed for small to medium faces, they enable you to quickly find the right adjustment thanks to the QuickFit strap. The DriWix triple-density face foam provides a good fit on your face and absorbs moisture to prevent fogging. It is helped by a ventilation system that limits condensation.  Features of the Smith 4D Mag S:  Fit Small/Medium QuickFit strap: quick and simple adjustment  AirEvac ventilation system DriWix triple-density face foam Perfect fit with Smith helmets: ventilation, comfort Silicone strap Hard case + microfibre pouch included Goggles Smith ---4D Mag S Claws Blackout Chromapop Sun Black + Chromapop Storm Blue Sensor Mirror
