Product Summary:

One K Defender AIR Suede Helmet

Are you looking for the perfect fit from a helmet, but your head is not exactly round nor exactly long oval? The One K “Defender Air” is the solution for all those in-betweeners. This helmet has an inflatable liner that adjusts exactly to the rider's head size with just the push of a small button. The three hidden air pockets inflate by depressing a concealed air pump until the exact fit is achieved. They deflate just as easily.

The One K “Defender Air” helps stabilize issues for riders with "hair" that otherwise are subject to the fit of the helmet being at the mercy of the hairnet. Once you feel the helmet snug on the entire circumference of your head, the fit just feels secure overall.

One K Helmets boast the perfect synergy between advanced technology and aesthetically pleasing design. With enough features to appeal to those seeking everything a helmet could possibly offer, wrapped in a package that traditionalists can appreciate, One K has the best of both worlds.
