Poly-Max flags are skillfully crafted of 2-ply 100% polyester bunting, with embroidered stars and sewn stripes. They are extremely durable, with an open-weave construction that reduces wind resistance, lessens abrasion and increases flag life. Poly-Max flags are extremely durable, and are ideal for industrial and institutional applications. They are light-fast to protect against UV rays and wet-fast to prevent bleeding and migration of the dyes, with color that is engineered to stay bright.
