This is just like the long sleeve tees for adults. Made by SOS in Texas. SOS organic cotton products are 100% Made in the USA by American workers being paid a fair wage.

The natural color items will reflect the type of growing season we have in the color of the fabric. Some years, cotton is darker and the tees are occasionally striped with color variations. This actually looks very nice.
