The Ronhill Aspiration Short Sleeve T-Shirt is manufactured with Vapourlite fabric, designed with a lightweight knitted construction. They draw moisture away to the outer surface, which then evaporates into the air, enhancing comfort whilst running. Garments manufactured from Vapourlite are breathable and quick drying. Mesh panels in key heat zones work with the Vapourlite fabric to allow further ventilation and breathability, helping to keep you at an optimum temperature and comfort level. With flat-lock seams, this top reduces chafing and keeps you comfortable during training. This reflective shirt will keep you visible whilst running in low light conditions.
