Using this T - shirt is super easy. Just put it on and enjoy its comfort whether you're hitting the gym, going for a jog, or simply lounging at home. Before buying, make sure to check the size chart as it has a slim fit and runs 1 - 2 sizes smaller than regular. When it comes to maintenance, you can machine - wash it in cold water with like colors. Avoid using bleach to keep the 3D Venom print looking great. Hang it to dry or tumble dry on low to prevent shrinkage. If there's a slight color difference due to your monitor, don't worry, it's normal. Also, keep in mind that there might be a 2cm/1 inch measurement inaccuracy because of hand - measuring.
