With the F3 Carbon being the lightest of the F3 series, the F3 ECE-only helmet sits squarely between the F3 Carbon and F3 ECE/DOT.
Wanting to further refine the helmet, KLIM used a Fid-Lock magnetic quick-release buckle for easy operation while wearing gloves. Already a proven feature on the F5, the Fid-Lock buckle makes fiddling with d-rings a thing of the past.
As with the other F3 helmets, a triple-density EPS layer and three shell sizes and EPS thicknesses will provide the best fit experience possible. The direct-vent shell and EPS design is also carried over to the F3 Carbon, meaning airflow has a highly efficient path to help cool you down.
