What is Polyester / Coolmax Polyester (56% + 33% lining)?
Polyester is a synthetic fabric made from polyethylene terephthalate (PET), a type of plastic derived from petroleum. It is manufactured through a chemical reaction involving coal, petroleum, air, and water, resulting in a durable and flexible fiber.
Polyester is popular in clothing, especially sportswear, due to its moisture-wicking capabilities and lightweight nature. Health concerns are generally minimal as it is considered safe for use in textiles, though some individuals might experience skin irritation from polyester fabrics.
When you see polyester on a label, it often indicates a focus on durability and functionality, particularly in athletic and outdoor gear.

Scout's take
Synthetic lining sitting directly against sensitive chest skin. Sheds microplastic fibers during washing.
