To use these men's t-shirts and premium t-shirts, simply put them on like any regular shirt. When it comes to washing, use cold water and turn the shirts inside out. Wash them with clothes of similar colors. Only use non - chlorine bleach if needed. After washing, you can hang them to dry for the best look, or you can use the tumble dry setting on cool or low heat. Don't use fabric softener as it can make the colors fade. Also, avoid ironing and dry cleaning these shirts to keep them in good condition.
