These men's cotton trousers are super easy to use. Just put them on like you would any other pair of pants. When it comes to choosing the right size, don't forget to check the size chart as each item has its own. If you're used to US sizes and want to try Asian sizes, follow the example we gave in the product description. For maintenance, you can machine - wash them in cold water with similar colors. This will help keep the cotton fabric in good condition. Hang them to dry to avoid any shrinkage. You can iron them on a low - heat setting if needed. Also, keep in mind that these pants are mid - weight, so they're suitable for different seasons. Wear them casually on a weekend or for a safari - style look when you're feeling adventurous.
