Hi, this helmet is for you “in-betweeners”. Yes, you know what I mean: your head is not
exactly round, and not exactly long-oval. You need something that fits your head like
a glove, no matter your hair style. The One K Defender Air is the solution. Let me show you how it works. This helmet has 3 air pockets in the minor
that adjust exactly to the shape of your head. And it’s easy to do. This doesn’t seem quite right. So, just put this a few times and it fills
three bladders with air to create a perfect fit. Much better, but maybe one more pump. The perfect fit! Not every helmet fits every head, but the
One K Defender Air is the option for you “in-betweeners”.
