My son was refusing to wear his school uniform, complaining that the fabric was "itchy". Solved the problem by getting him these.
He is 4 years old, and I got the small size. The length of the tank is rather long, and the arm holes are big on him, but hey, it resolved the issue of him complaining about his school uniform! The tank material is thin, which is a plus point, as despite wearing 2 layers of clothing in a tropical climate, he does not complain about feeling hot.
However, I docked one review star coz the seams of one of the hems was not properly sewn, after after a couple of washes that particular tank is starting to look rather ragged at the hem. The other 4 tanks are ok though. I don't think it's an isolated problem as one of the other reviews I read had the same issue. So either Hanes has to improve its quality control, or it is periodically slipping one defective tank into a pack - I'm not sure which.
