Much smaller than the normal Youth Medium loose fit UA shirts I normally buy in store.This shirt is nice looking and the material is soft. I bought this for my son who plays golf. This was not offered "Amazon Prime" but assumed Under Armour sizes would all be the same, and they are NOT! My son normal wears a youth large and still has room to grow but this shirt fit him snug. I asked if I could do an exchange and Under Armour would not. They said I could return it and pay shipping back and then reorder New and pay shipping again. Very disappointing to hear this from a big successful company.Anyway, I just wanted to give heads up to buy size up so you do not run into the same problem I did.Very soft and comfortable. Thin which is nice for warm weather! It’s a little slimmer for which is perfect as I have a hard time finding nice shirts for our son that do not look big and baggy on him. Got it very fast. Exactly what I was looking for for dinners out on our vacation! Love it!My son doesn't like the fit of cotton and wants to only wear athletic shirts. This is a perfect compromise when he wants to be comfortable and I want him to have a collar and look dressed up!A little see through, but nice.What expectedFabric is thin but fit is as expected.This is really a thin shirt, will but will be nice in hot weather. Size up as it runs small.I'm trying to get my nephew to like golf as much as he likes football so I've bought him some second hand clubs and this new under armour golf polo shirt. The quality is good and I like the colour. If Under Armour is good enough for Jordan Speith, well enough said.Polo di tessuto tecnico leggerissimo e traspirante, perfetto per attività sportiva, ma anche per andare a scuola. Mio figlio è molto contento. Taglia S va bene ad un bimbo di 6/7 anni.
