Ballistic Performance

We have produced and exported over 350,000 helmets around the world since 2001. Our modern plant manufactures light weight, high performance and low cost helmets of the highest quality.

All helmets can be manufactured with a choice of harness described under HARNESSES in this section. A choice of visors can be fitted to most helmets as can be seen in the VISOR section.

Zebra Protection’s new ballistic testing- and research facility insures product development, new materials research and quality control. Our standard products are designed to meet the standards defined by the NIJ (National Institute of Justice) in the USA
which is a worldwide recognised Organisation. Our products are also designed to meet our customers varying standards and requirements.
