SINGLETRACK TRAILBLAZER The last thing you want to be thinking about in the middle of a long backcountry ride is your helmet. It should be well ventilated. It should protect your head. And it should fit so well that you don’t know it’s there. The Sixer takes to the trail with Bell's integrated MIPS technology resulting in a sleeker closer-to-the-head fit that combines with their Float Fit system and proprietary Sweat Guide to ensure unprecedented comfort in a helmet.
