Backpack
Nylon, canvas and oxford cloth are the most common materials used in backpacks.  Nylon, a type of plastic, is favored for its durability, light weight, and water resistance.  The plastic can be melted down and processed into fibers that are then woven into backpacks.  Oxford, a synthetic material made from nylon or polyester, is cheaper but still durable enough for everyday use.  However, it may lose wear resistance over time if overloaded.  Canvas is also a common material used in backpacks for its strength and durability. Made from cotton or a blend of cotton and polyester, canvas backpacks are favored by those looking for a more rugged style. While not as lightweight or water-resistant as nylon, canvas backpacks are known for their sturdiness and long-lasting durability. Ultimately, the choice of backpack material depends on the intended use.
