Workman (Purchased at Workman Colors) Short-Sleeved Shirt with Ventilation Color: Blue / Stripe Material: 100% Polyester Size: M Width: 55cm Length: Front 61cm, Back 66cm Sleeve Length: 24cm I bought this but haven't had a chance to wear it, so I'm selling it. It has ventilation on the back, so it's breathable and less likely to get stuffy. It also has water-repellent properties. It looks good worn on its own, or open with an inner layer or T-shirt underneath.
