Adidas Compression Short Sleeve Shirt Techfit With its appropriate compression design, this shirt not only supports muscles during exercise but also provides moderate breathability. It employs an ergonomic design, preventing the garment from shifting even during intense exercise. I purchased this but am selling it because the size didn't fit. Size: Width: Approximately 41cm Length: Approximately 59.5cm Although it is new and unused, please understand that it has been stored at home before purchasing.
