To use this tee, simply put it on and enjoy its comfort! When it comes to washing, use a gentle cycle with cold water to keep it in good shape. Avoid using bleach as it may damage the colors. Hang it to dry or tumble dry on low to prevent shrinkage. The pigment dye colors have natural shade variations, so don't be surprised if you see some differences. This tee is made to last, but with proper care, it will look great for a long time.
