Tri-laminate is a type of material made from three layers of different substances, typically combining a waterproof outer layer, a breathable middle layer, and a soft inner layer. This construction provides durability, comfort, and protection against various environmental conditions, making it popular in outdoor gear and clothing. The three layers work together to keep moisture out while allowing sweat to escape, ensuring the wearer stays dry and comfortable. Tri-laminate is commonly used in products like jackets, tents, and footwear, enhancing performance in activities such as hiking, skiing, and camping.
