Inspired by the A-10 flight pants issued during World War II, the original design was made from lightweight canvas or twill and lined with wool or down to keep the crew warm, that's make it gets thick and heavy. We’ve reimagined this version using heavy-duty twill fabric for added durability. The pocket configuration has been updated with two front slant pockets, cargo pockets at each thigh, and flap pockets at the front of each lower leg. It also includes exterior buttons for attaching braces.
