👉 "Permatex" refers to a fabric made from polyurethane, commonly known for its light weight, water-resistance, and breathability in clothing. It's typically used in outdoor gear, camping wear, or athletic apparel because of its superior water resistance qualities. The term "permatex" can also be found in the Bible as referring to a specific type of leather called Perma Leather, which was traditionally used by ancient Romans for military uniforms and armor.
