| Custom Fit Liners |

|

|
| Custom fit helmet liners are
leather covered urethane foam. They are
made from a wax mold of your head. The
helmet will precisely fit your head and
face. We will send you a fitting kit that
includes a wax mold and instructions. You
can fit the mold to your head and return
it. We guarantee that your helmet will
fit. The $35 cost of the kit will be
refunded when you order your helmet. |
