Worn for two seasons. Since there is a feeling of wear, it is recommended for washing and replacement. The design is simple and goes with any style. The fabric is soft and seems to absorb sweat well, so I think it can be used in seasons other than summer. There are some pills on the inside, but there are no noticeable pills on the outside. Also, the pills on both the inside and outside are not that noticeable to the touch (not bumpy). Sleeve Length...Long sleeve Design...Solid
