Engineered to maintain their good looks despite long exposure to wind and sunlight. Improved steadfast colors, thanks to a patented DuPont process. Unlike heavy sailcloth flags, ours minimize premature wear on sticks and cups, and decrease the chance of flagsticks being blown out of cups.

Denier is a good measure of strength and durability when you&#039;re comparing two deniers of the same material. For example, a 200D nylon flag is not as strong as a 400D nylon flag sold by ShopTJB. However, when you&#039;re comparing between different materials (for example, nylon and polyester) all deniers are not equal. Since nylon is a stronger material than polyester, 400D nylon is actually stronger than 600D polyester.
