This T - shirt is super easy to use. Just put it on like any other shirt and enjoy the comfort it brings. When it comes to washing, use cold water and mild detergent to keep the colors and fabric in good condition. Avoid using bleach as it may damage the anti - bacterial treatment. Hang it to dry to prevent shrinkage. Since it's made to order, please be patient during the 7 - 10 business days processing time. And remember, it's unisex sizing, so it fits both men and women well.
