Klim F5 ECE Helmet

When Klim set out to build this new F5 helmet they had three goals in mind. Make it vent well at both high speeds and in slow riding, make it fit well, and KEEP IT LIGHT. They nailed these three goals. To accomplish the ventilation goals the F5 has huge vents on top which let radiant heat escape. This is immediately noticeable when you're feeling cooked from working hard on tight singletrack. This helmet feels feather light in your hands. Less weight on your head translates to less fatigue. Additionally, less weight on your head in a crash means less chance of injury to your neck. The eye port opening of this helmet is HUGE, and will accept any of the newer oversized goggles. In addition, this helps with ventilation.Comes with a helmet bag, extra parts, breath box, and wind stopper liner. Full carbon fiber shell Medium helmet weighs 2 lbs., 11 oz.
