Zamp Helmets should be releasing the all new RZ-34 in a few weeks.
One of the most versatile helmets we have seen come into the market, at a pretty decent price. The basic RZ-34 helmet will be priced at 219.95 and the RZ-34 Top Air at 249.95. The top air nozzle can also be purchased separately and easily installed into the basic RZ-34 model, should a driver decide to utilize a forced air or Cool Shirt air system in the future.
Other RZ-34 options will include a Rally type visor and an SAH2010 model, with the 6mm threads and backing washer preinstalled for easier head and neck restraint installations.
