Always read the title
Size: Medium
Color: (011) Mod Gray Medium Heather / /
Bought it by mistake. Thought it was men size not a boy since. Didn’t stopped to read the title. Almost give it a 1 star review, but I realized it was my bad. Gifted it to my son, and he really liked it a lot, so thumbs up for that.

Fantastic quality and great fit
Size: X-Large
Color: (011) Mod Gray Medium Heather / /
Absolutely great fit for my older son, I feel like it’s a bit too large but it did shrink up some after a wash so it’s like a relaxed fit for him right now. Soft and light material, really great for everyday wear. I like quality and fit, looks great with shorts or jeans so it’s definitely very universal. I’m happy with it.

Very Nice Under Armour T-shirt
Size: X-Large
Color: (011) Mod Gray Medium Heather / /
This 'Under Armour' (Project Rock Payoff) tshirt is of decent quality; it's made with lightweight material that's great if you're playing sports or everyday wear also. This shirt is made for boys, but obviously anyone could wear this. This seems to fit true to size, and has some stretch to it also. This is a nice shirt, with a unique design; decent for the pricing also (in my personal opinion).
