Question: What size is medium
Document: This shirt looks great and I think that my son will love it but I did order the largest size and he is only a med size on everything else. It will last more than just a few months now there is a little growing room for him.
But fits really snuggly - almost too small for my son who I really thought would get more than one season out of this expensive purchase, one wash shrunk it a whole size.
have to peel it off him or sneak it to the washer while he sleeps. My 11 year old son wears it EVERYDAY since Christmas and it is holding up excellent.
This sweatshirt was everything we expected it to be. The fit was perfect. Material is high quality as always from Under Armour. Very pleased.
This hoodie was exactly as described. I knew what I was ordering when I ordered it. I was in Cabelas and seen this hoodie so  i looked it up on Amazon and it was several dollars cheaper, no tax, no shipping great deal.
The sweatshirt itself is basically fine. A bit pricy, but basically fine. Dealing with Under Armour was not so good. The package only had to be shipped three hundred miles (Baltimore to NY) but it took ten days to arrive. I bought this as a gift, a week ahead of time, thinking that would be plenty. Not so much.
Our 11-year-old grandson was thrilled with this sweatshirt. Nice quality from his favorite brand in his favorite color. It was a can't-miss gift.
My son loves his sweatshirt!!!!! He says it fits good and is very warm and fits comfortable. The quality is also good
My son got this hoodie for his 10th birthday and he LOVES it. It fits perfectly and he says it is warm without being bulky. It also has waterproof technology so even if he wore it in the rain, he wouldn't get wet.
My grandson loved this, wears it all the time, must be warm, loved the camo look and orange letters on the front
Answer: no
