“Works very well in warm weather conditions. Some materials makes sweat smell really bad, but I don’t experience that with this shirt! I bought a size with help from the size guide (comparing size with another brand) and it was true to size, however, I experience it to be very tight in the hemline and the shirt slides up to the waist. Would be better if it was shaped a bit more for us “curvy” women (I’m usually XS in tops and S in bottoms, bought this in size S).”
