Product Testimonial

testimonials from the field

L.B., Military Times

The helmet is 20% lighter and promised increased ballistic performance. Lighter and stronger is always better. But the Batlskin [MPAS] boasts two features that caught much attention. The mandible guard provides blunt force and fragmentation protection for the lower jaw. One platoon sergeant said it should be required for every vehicle gunner. Although the guard makes it tough to position a carbine in your shoulder and take aim, it can be quickly removed. Soldiers also said the three point front mount tightly secures NODs or night observation devices, ridding the war fighter of that pesky, noisy rattle.

What I liked most about my Batlskin Head Protection System was the removable visor. Due to its high quality I would recommend this product.
