Using this men's body shaping compression vest is a breeze. Just slip it on over your upper body like you would a regular vest. You can wear it during your daily activities or when you're working out at the gym to help you sweat more and shape your midsection. When you're done using it, take it off gently. To keep it in good condition, hand - wash it in cold water with a mild detergent. Don't bleach it. After washing, let it air dry. Avoid wearing it for an extended period continuously. If you feel any discomfort, take it off right away.
