Comfort and exceptional ventilation are the two main features that you’ll instantly notice regarding our new mountain bike helmet. We could categorize it in trail, all mountain or enduro, but it’s simply THE ideal mountain bike helmet. Its reduced weight doesn’t affect its protection benefits, and the addition of the ERT technology brings a real progress in case of low speed impacts. The AllAir will quickly be at the heart of our mountain bike range and recognized as our best seller, guardian of our own design and our modernized but eternal lines.
