I was wearing a top that only had a mesh panel in the back and I found that I was getting too hot everywhere but where the panel was. I saw this shirt and it is exactly what I was looking for. Its as cool as the mesh panel part of my old workout shirt everywhere! Also, I love the high neck and that the straps go all the way to the shoulder because it completely covers my sports bras! I am petite, just under 5' tall and this shirt goes to about the bottom of my hip on me. I wear a size small in the women's clothing at Kohls, I ordered a small in this shirt and it fits perfectly.
