Em, not so much
Let it be said that I completely LOVE the Ex Officio underwear (I've replaced my whole nappy drawls collection with them)The shirt is made of the same material, however, something is truly missing in the comfort department, I don't know if it's weird seams (of which, there are some in the neck and armpit area) or that the fabric that feels good on my boys just don't feel so good on my chest and back. Something about that waffled fabric grabbed at my chest hairs and didn't want to let go. If I'm going to pay $40 for a performance T-shirt it better be comfy as hell.
Sent this one back and traded up to an Icebreaker GT series. Mo pricey, yes, but waaay more comfy.
