"Fits a little big, dries fast. Great layering top."
"Great undershirt breaths well"
"exactly what I was looking for, the feel and the style"
"Sweet comfortable top, keeps me dry and guards against the sun."
"I’m a little hesitant to decide whether I like this shirt. I love the color, but the sleeves aren’t as long as I’d like them to be. The fit around the body is relaxed but still has some shaping which I like!! Overall a good lightweight activewear purchase."
