Drill is a durable cotton fabric woven with a diagonal pattern (twill) that’s most commonly used to make khakis.

It’s most common in khaki bottoms, and also used for shirts, safari jackets, sneakers, military uniforms, and chef coats.

Drill is a robust fabric that is easy to maintain.

Drill does have a tendency to wrinkle, but will often be treated with a wrinkle release finish, which makes it even easier to care for.

All cotton twills are easy to clean. They are easily cared for at home, or can be dry cleaned.
