The G18 Twill is made from 100% cotton twill, a fabric long valued for its strength, resilience, and subtle texture. Twill is woven in a distinctive diagonal pattern, which gives the material a natural durability and a soft drape that moves with you. This weave also makes the cotton more resistant to creasing and wear, allowing the jacket to retain its shape over time. With a slightly heavier weight than regular cotton, twill provides structure without feeling stiff, while developing a gentle patina with age.
