A cycling jersey is a specialized shirt worn by cyclists during rides or races. It is made from lightweight, breathable materials like polyester to help keep the rider cool and dry. The jersey is designed to fit snugly to reduce air resistance and improve performance. It usually has short sleeves, but long-sleeve versions are available for colder weather. Many cycling jerseys have pockets at the back for carrying small items like energy bars or a phone. They also often feature bright colors and reflective elements for safety, making it easier for other road users to see the cyclist.
