The Salomon Driver Pro Sigma MIPS Helmet is ideal for skiers looking for the combination of protection, style and function. The helmet's shell and liner are separated by a low friction layer which allows the helmet to slide, noticeably reducing trauma to the brain in the case of oblique impacts. You'll have extra piece of mind knowing that your noggin is getting extra protection with this type of technology and has passed the EPS4D Smart Safety standards. In addition to being safe, it's quite stylish and full of high-end features like the integrated Custom 360 dial that lets you tighten or loosen the Driver Pro with a twist of dial located in the rear of the helmet. This can be done on the fly with gloves or mittens on and takes just seconds. A removable, washable liner comes out easily and can be cleaned. A Sigma Blue Lens Goggle is built into the helmet for seamless integration. For skiers looking for a all-in-one goggle/helmet combination, look no further than the Salomon Driver Pro Sigma MIPS Helmet.
