The Speed Polartec 1/2 Zip M by Dynafit is a technical long-sleeve shirt made from Polartec Power Grid fleece made from recycled polyester. The fabric quickly wicks away moisture and dries quickly, so you stay more or less dry even during sweaty activities, as long as it's not raining. The shirt has a half-length front zip, a chest pocket with a zip and all-round elasticated cuffs and hem, which are also made from elasticated fabric.
