Our Combat Stress cycling jersey is 100% breathable polyester wicking fabric, to help draw moisture away from the skin and prevent overheating. This uni-sex cycling technical t-shirt is part of our active wear range, making it perfect for training. What's more, the charity logo and colours are produced by sublimation printing or dye printing. This method doesn't leave rough edges like screen printing can and therefore doesn't cause irritation. Do not tumble dry.
