MO Tested: 6D ATS-1 Helmet Review

With and without the chin curtain and rear neck cuff. The ATS-1 proved to be a quiet lid while riding with the chin curtain and neck cuff installed. Emergency tabs on the cheek pads are nicely obvious. The chin strap, though, is about an inch longer than it needs to be. We were told 6D is working on small improvements such as a shorter chin strap and a new material for the comfort liner.
