A type of [[body armor]] designed to protect from from explosive weaponry such as anti-aircraft artillery ("flak" is a German contraction for [i]Fliegerabwehrkanone[/i], "aircraft-defense gun") or grenade fragments. Its prominent usage was by the US military during the [[Vietnam War]], but cannot provide protection against higher velocity (rifle) bullets.

Compared to more modern soft bulletproof vests or plate carriers with rigid-looking front, flak jackets look more loose-fitting as if it they have soft quilt, having buttoned or zipper front top, collared appearance, and many of them feature [[pocket]]s or [[pouch]]es.
