My kids and I love this shirt! I bought some for them (in sequenced sizing so they could wear for a few years under their uniforms on cold mornings) and it works great for that! They have both worn them under their uniforms when they need an extra layer. It layers well (for my daughter in softball, and my son in soccer and he'll use it for baseball for the 1st time this weekend). I ended up getting one for myself because of the B1G1 free sale and I'm so happy I did! My son and I both wear ours as a sweatshirt too! It's not a heavy material but great for the casual Friday since I bought mine in school colors. It's a loose fit, not the tight compression fit (unless maybe you bought it smaller).
