I used this for gymnastics class. It's 100% polyester, so it dries quickly. The size is 120, but it runs a little small, so it would be a good fit for children around size 110. There are thumb holes, so it can be used as a rash guard in the summer. There are a few thread pulls, please check the images. On the collar, the back of the left sleeve, and two places on the front of the right sleeve. This is a used item that my child wore, so please consider this before purchasing.
