Charles Tyrwhitt Shower Proof Rain Coat, Stone

This raincoat has all the hallmarks of a wardrobe staple with its breathable cotton fabric and showerproof finish. It's understated yet brimming with functional features, such as a back vent for ease of movement and four handy pockets.

Thanks to the innovative crease recovery, it looks crisp even after long commutes and the buttons are neatly tucked away under the concealed placket.
