Armwarmers are clothing accessories designed to keep the arms warm while allowing for freedom of movement. They are typically made from stretchy materials like spandex or wool and can be worn over short-sleeved shirts or alone. Armwarmers are popular among athletes, especially cyclists and runners, as they provide warmth without the bulk of a full sleeve. These garments come in various styles, colors, and lengths, catering to different preferences and activities. Some armwarmers even feature reflective materials for added visibility during nighttime activities. They are easy to put on and take off, making them a convenient choice for changing weather conditions.
