The purpose of the Nike Players top (AKA: Cold Weather Pro) is to keep the structures in the throwing arm pliable and supported. This is done by providing targeted warmth and stability to the high risk areas of the elbow and shoulder while providing ventilation and Dri-FIT benefits to keep the rest of the body cool and dry. 62% nylon/27% polyester/11% spandex with 79% polyester/11% nylon/10% spandex sleeves. Imported.
