“The fabric is moisture wicking and fast drying with two-way circulation to help keep you cool and dry while the IceFil® technology converts sweat into cooling energy. The brushed interior is ultra-soft on your skin and is stretchy enough to allow you to move freely in and out of the saddle. It even has antimicrobial qualities to keep you feeling fresh all day! Mesh inserts under the arms provide extra ventilation and breathability to help make sure you stay comfortable and protected from the sun this summer. 50+ UV protection helps block the sun’s harmful rays while the 1/4-length zip gives a sharp look and makes it easy to take on and off.” Used TS sun shirt! Has some pilling and a small hole on the sleeve.
