Description (copied from the manufacturer):

The popular nightvision long sleeve jersey just got better thanks to increased areas of reflectivity and the addition of two zipped hand pockets to help improve this classic commuter top. A comfortable thermal brushed back fabric will ensure that you stay warm on the ride whilst the large areas of reflective print and rear light loop will help you to stay visible in lower light conditions. This is a perfect go-to mid layer for cold weather commutes combined with a jacket, or used as an outer layer on the milder days.
