These Baltimore Ravens track pants are super easy to use. Just put them on like any regular pants using the zip cuffs. Wear them when you're working out at the gym, playing on the field, or just going out. Remember, since they're made of 100% polyester, they may not absorb sweat as well as cotton. So if you're doing intense exercise, you might want to wear a moisture - wicking base layer. For maintenance, you can machine - wash them in cold water. Tumble dry on low to keep the colors and graphics looking good. Don't use bleach as it may damage the fabric and the screen - printed team graphics.
