- Lightweight thermoplastic shell
- Inner Sun Shield with easy one-hand operation (open, close)
- Adjustable exterior air vents on chin and scalp areas

Sizing Your Zamp Helmet
The FR-4 helmet is available in sizes X-Small to 2XL.
Like many helmet brands, Zamp determines the size of their helmets based upon a driver's 'hat size,' the circumference around the head just above the ears, and along the top of the brow.
