The Rant is a skate inspired lid offering simplicity & style. Its low profile Hard-Shell construction sets the standard for what is a tough & reliable helmet. The Passive-Channel Venting directs air-flow between your head & the helmet. What is also great about K2 helmets is their custom fit liners, the Rant has a snap strap adjuster. This liner is also removable, so you can wash it, which is a great feature & unique to K2.
