Very well-made, nice heavy fabric.  The product description doesn't say whether the sizing is for kids or adults, but this shirt is TINY.  My son is a very small 12-year-old, about 4'6" and very skinny.  The small size is a little baggy on him, just big enough to wear next year as well.  The glow-in-the dark is fun.  My son is a Minecraft fanatic, very picky about his Minecraft  merchandise, and he LOVES the shirt.  He wore it to school and other kids loved it too.
