With a full rim frame and rubber nosepad, Havoc might appear pretty standard. But think again. On the outer edge of Havoc's lens is an intelligent ventilation tactic that allows for continuous airflow and helps prevent fogging. The Gargoyles G-Loc Hinge creates sturdy, designated open or closed temple positions. Co-injection construction combines two materials for a more durable vented nosepad, comfortable browbar and gripping temples. Like all ANSI Z87-2+ styles, Havoc exceeds the standards for high mass and high velocity impact protection, coverage and optical clarity. The ‘2+’ designation means you’re able to change the lenses to prescription lenses. The TR90-NZZ frame material takes flexibility and durability far beyond that of the more commonly used TR90. So gear up for your tactical mission, a 10K road race, or just another day on the job. With Havoc, eye protection is anything but standard.
