To use these pants, simply zip up the fly and adjust the internal drawstring and elastic for a comfortable fit. You can use the stacked cargo pockets to store items like pens, small notebooks, or medical tools. Put your daily essentials in the front pockets and keep important items in the back pockets. When it comes to maintenance, machine - wash them in cold water with similar colors. Avoid using harsh detergents. Tumble dry on low heat. Check the pockets before washing to make sure no small items are left inside. Also, don't iron directly over any printed logos or details on the pants.
