There are many uses for flasks and this pilot flask from, Hayes Tooling might be the most useful flask of all. Designed and used by air crew in the military, these flasks are made from tough polymer that will stand up to the abuse. Why purchase a cheap imported flask when this American made, military grade flask is available for a cheaper price? We purchased a large lot of these flasks and have them available in black, olive drab, and coyote tan.
