Charles Tyrwhitt's slim-fit blazer is a more modern jacket with slimmer through the chest and waist to give a more close-fitting and tailored silhouette. All Charles Tyrwhitt's fits now have a softer shoulder pad that still gives a smart appearance but also comfortable fit. For a faultlessly smart silhouette without having to get too hot under the collar, reach for a linen cotton jacket. Linen is anti-bacterial and wicks away sweat, while cotton keeps things smooth and comfortable.The single-breasted piece has neat notch lapels and straight flap pockets. AMF stitching keeps them in place for a clean aesthetic.
