Light, Stretchy, and Super-Breathable
Big fan of this fabric. It's semi-perforated (see pic) so it's highly breathable and very lightweight. Great for warm weather! Only reason I gave it 4 instead of 5 stars is due to the cut. I ordered the XS (normally wear a women's S or M / size 6) and it's still pretty wide/boxy. If you prefer a looser fit, this shirt is perfect. In sum, for me as a 5'6" size 6 woman, the XS fits very well in the chest & shoulders, wide in the waist, and a little short in length. But love the fabric and this will be great for warm-weather running.
