The 'Ninja by Nature' design is from Ryan Astle. These crewneck sweatshirts are available in sizes from S to 4XL. The 8.5 - ounce material is an 80/20 blend of ring - spun cotton and poly, with a removable tag for ultimate comfort. The twill - taped neck and locker patch help prevent stretching. Care is easy: machine wash cold, inside out with similar colors. Use non - chlorine bleach only when necessary. For the best look, hang dry after washing, or you can tumble dry on cool/low heat. Avoid fabric softener as it may cause fading. Do not iron or dry clean.

To use this awesome Ninja - themed long - sleeve t - shirt, simply put it on and show off the cool design. When it's time to clean, remember to turn it inside out and wash it in cold water with clothes of similar colors. Only use non - chlorine bleach if there are stains. After washing, you can hang it to dry for the best results, but if you're in a hurry, you can tumble dry it on a cool or low - heat setting. Don't use fabric softener because it might make the colors fade. And please don't iron or dry clean it, as that could damage the fabric and the design. Keep these tips in mind, and your t - shirt will look great for a long time.
