These are genuine U.S. Army PFU (PHYSICAL FITNESS UNIFORM) training pants, adopted and issued by the U.S. Army. These pants are worn by U.S. soldiers during training. The lining is made entirely of mesh material for breathability, and they are designed to withstand intense training. The slightly textured fabric reduces the rustling noise when worn, and the pants are quick-drying and highly breathable. The waist and hem are elasticized with rubber shirring, and the zippers at the hem allow for easy on and off, as well as temperature regulation. The waist also features a drawcord to enhance the fit, resulting in pants that are very easy to move in and comfortable to wear. The design, with double-reinforced fabric around the knees and hips, is a detail that allows you to wear them for a long time in tough conditions. Compared to other nylon pants, they have less sheen and are easy to incorporate into everyday wear without being overly sporty. They are perfect for training, and their high fashionability makes them a great match for sweatshirts and hoodies. They are one of the items that have become scarce and expensive in recent years, so they are a military wear item that you won't regret owning! Note: Due to being a genuine product, there may be individual differences in size. Color: Black Material: 100% NYLON Product Condition: Purchased as a genuine new, unused deadstock item and worn only once or twice, so it is in beautiful condition.
