Bought three for my son
He's starting college and needed tees that looked put together for class but weren't dress shirts. Got him one in each color. He texted me after the first week and said the black one is already his favorite shirt. Coming from a 19 year old that means something. The fit looks great on him (he's 6'1, lean build) and they wash well.

Shoulders fit REALLY well
I have broad shoulders and a shorter torso which makes most tees look weird on me. Either the shoulders are too tight or the body is way too long. Large in this one nails the shoulder width and the body length is about an inch shorter than most larges I try. The gray looks clean and the sleeves sit right on my arms. Exactly what I've been looking for and I've tried a lot of brands to get here.

Fits clean on a bigger guy
I'm 6'0 240 with thick arms and a gut. XL fits through the chest without pulling and the arms have room to move. Most tees either cling to my stomach or they're so loose I look like I'm wearing a tent. This one threads the needle. Navy is my go-to. Might grab a second one... actually I'll just order all three.
