Klim F3 Prizm Helmet (LG Only)

The F3 snow helmet offers a good balance of features and performance, and uses the same precise hand-laid construction process found in our carbon fiber helmets. We’ve moved the beloved F3 snowmobile helmet away from DOT certification, retaining an ECE-only certification for the sole purpose of reducing weight. A lighter helmet means less fatigue, which means a better day on the snow.
