The Perfect Fit for Inbetweeners!

The One K Defender Air riding helmet is the perfect helmet if;

• Your head is not exactly round, nor exactly long oval!
• You are between standard helmet sizes, or just plain hard to fit
• You like to adjust the fit of your helmet throughout the day

So how can One K Defender Air riding helmets be so adjustable?
The secret is in the Air pump system that provides the ultimate in comfort & custom fit. The 3 hidden air pockets in the liner inflate by depressing its concealed air pump until you get the fit you want.
