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
- You sometimes wear your hair up, other times down
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.
