In the warmer months (I'm in AZ, so warmer means 90 degree temps) when I run outdoors, I usually wear a running skort, sports bra, and tank , and sometimes even that seems like too much. So, I try to stick with breathable fabrics and generally prefer mesh tops and bottoms. The Free Me Tank material is like the skirt on the Gym Girl Ultra. It's relatively lightweight, breathable, and moisture-wicking, but not mesh, so not as ventilated as I'd like. The tank is cut rather square. I'm 5'1", 108 lbs and got the XS and it fits me like it does the model pictured on Amazon. I find it a bit too long and wide at the bottom. While it's not in the way while I run, I do find myself thinking about it a bit more than I would like.

It is tough to find something short enough for a petite woman and I'm not a fan of fitted tanks or camis (yet?)If you're looking for something a bit more modest without being too covered up, this tank will work. My other sleeveless tanks are mostly the inexpensive C9 brand, which I feel are a good value.
