I got the yellow shirt through my gym (they work with Reebok, so there's always some stuff around from Reebok CrossFit for the coaches) and love it save for one issue... ...it's comfy, holds up great during workouts, and is super cool (temperature wise). The one problem I have is that it is pretty good and see-through. If my nipples were the same color as the rest of my flesh, or if I didn't have tattoos, you'd no idea, but I put the shirt on and it looks like I'm blasting nips all over the place, and there's no mystery about the body art. I'm all for taking the shirt off during workouts, and I often do, but having a see-through shirt is a totally different story.
