When I was first given the attractive, feminine EIS Coolshirt to test at the end of February, I was critical. Since it was made out of a nice, lightweight, and soft fabric with SPF 50, I perceived it strictly as a summer item. But after I wore it around the barn, on a few trail rides, and in a covered arena, I became a believer. Whether I wore the EIS shirt by itself or under my winter riding jacket, in which I sometimes start to sweat when the temperatures get warmer, the EIS Coolshirt kept my body-temperature at a comfortable level at all times. No sweaty or sticky feeling, no body odor. The shirt is nice to look at and is well made. It is easy to wash and dry, and it stayed true to form after it came out of the dryer. I definitely would buy one to keep me cool during the hot summer months. I recommend this shirt to all serious horse women!
