I wear a medium and the fit is fine although if you are looking for a stretchy, tight fit, go a size down. The size is more generous than other workout tops I own but I'd rather the top be looser than worry about showing muffin-tops. I absolutely love the print on the front. It's really cute and it's so comfortable and soft, I could sleep in it. I also love the green straps, which contrast nicely with the rest of the top in black. I would buy more of this design if it came in a variety of colors.

I liked the design of this shirt, but it does run large. Size yourself according to the sizing chart -- I'm a medium in almost everything I have but I definitely should be a small for Icebreaker. I also bought another Icebreaker cami in medium -- this one was larger than that one. The shirt itself was adequately thick, and with the shelf bra you'd have two layers of merino wool over your bust area. Overall I would have kept it if it actually fit.

I wear this tank climbing - it's great because you can sweat in it and wear it a few times in a row due to the fact that it's merino wool so it doesn't get stinky. It's soft, and the built-in bra is supportive enough for me (34B) as far as climbing goes (not enough support for running, but climbing/hiking is ok). The yellow piping and straps are quite a bit brighter in real life than in these pictures, but it'll probably fade a bit. I gave it four stars because the built-in support isn't quite as supportive as some other tanks I have, but I still love the shirt.

Can't beat merino wool, no more synthetic for me. Unfortunately, ran out of my size in this style. It is sized large, I bought a size L based on the sizing chart but should have got a S because my other Ice breaker shirt is S.
