LANBAOSI 2 Pack Boys Compression Base Layer Shirts Athletic Sports Size 5

These seem like good quality. My son liked them. He is 7 and we ordered the 7. They fit well as a regular fitted shirt. I bought them for the compression factor though so I think they will be perfect for next year (which is what I was hoping for). If you want them to be tightly fitted snd offer compression, I'd order a size smaller than your usual. I also like the white stitching...it offers a bit of design so that the shirts look cool on thier own but still simple enough to wear under a Tshirt.

For a nice snug fit, get a size smaller. My son plays tackle football and this is an easy way to look like he has the cool arm sleeves. He loves it.
