These are sampled from the M-44, also known as "monkey pants," which were adopted by the US Marine Corps (USMC) in the 1940s. The eye-catching large hip pockets are said to have been designed for crawling. Made of durable herringbone fabric, you can enjoy the aging process of this garment. Many manufacturers have sampled this design, but I think this one is quite faithful and cool.
