These are the very popular Mobstyle MOSH pants. They have zip pockets, making them suitable for a wide range of activities such as running, festivals, live events, gym workouts, and martial arts training. The size is L. The fabric is lighter and reinforced to accommodate any movement. This model does not use Velcro. The size can be adjusted with the inner drawstring at the waist. I intended to use them, but I haven't had the opportunity, so I'm putting them up for sale. They are unused and have no noticeable stains. Please consider purchasing them. Size L Waist: 76cm～104cm Length: 50cm Material: 93% Polyester, 7% Polyurethane This is a self-measurement, but please use it as a reference.
