One of your greatest weapons is your vision. Our Wiley X SPEAR meets the MIL-PRF-32432 ballistic safety standards for optical quality and high mass/high velocity impacts. Despite the bold frame, the SPEAR is lightweight and can be worn comfortably for extended periods of time. The SPEAR's removable Facial Cavity(TM) Seal helps provide extra protection by preventing dust and dirt from getting into your eyes. Designing protective eyewear for the brave men and women that protect our country is an honor that we take seriously.
