Klim F4 Anniversary Edition Helmet

I'm going out on a limb to make a bold statement here. After 10 years of making sweet technical riding gear, Klim has fine-tuned its airy F4 brain bucket into what might be the most comfortable helmet in motorsports. With 41 air-craving intakes, this lid keeps your head cool yet safe, exceeding M2000, M2005 and U.S. DOT standards. It's the next best thing to riding without a helmet but still protecting you with its construction of fiberglass, carbon fiber and Kevlar.

While testing the helmet in the Amazon Basin, I was surprised to actually feel a cooling gentle breeze in my hair while riding in the triple-digit heat. After riding in hot temps, you take off the helmet and your Justin Bieber hair isn't soaking wet, unlike traditional helmets that turn your fro into a dripping wet mop. At first glance, I had my doubts about the large vents. I was worried that dirt, sand and random bugs would filter through them. They don't. Surprisingly, the helmet didn't fill up with sand even after I took a header on a sandy beach.

This first truly vented helmet isn't just for the summer months. The helmet was originally designed for snowmobiling and has no problem in cooler temps. Preventing brain freeze is easy; simply pop in the included cold-weather liner with Gore-Tex Windstopper technology. It also comes with extra cheek pads, a breath deflector to prevent fogging on those cold days, a really sweet padded helmet bag with exterior pockets for the spare visor and an extra visor bolt (no tools needed). -Mike Calabro
