Whether it's been a few seasons since you purchased a new helmet or you're just getting into cycling, the Tonic Helmet from Lazer is an excellent choice as it offers protection, style, and a refined fit for riders of any discipline. On its outside, the polycarbonate in-mold construction is used for the shell promising durability and keeping weight to a minimum, while 28 large vents increase the airflow making sure you keep a cool head on those long summer rides. Instead of the Advanced Rollsys System we see on its top-tier helmets, the Tonic trades it for a TS+ dial at the back of the helmet. It controls a basket securing a large portion of the back of the head, offering both vertical and horizontal adjustment and keeps the helmet in place throughout the ride. A quick turn of the dial assures a snug yet comfortable fit that's adjustable on the fly. Final details include its reflective decals which provide increased visibility at night, a plus for any bike commuter.
