Forclaz Trek 700 3-in-1 Jacket £140

Is this the ultimate hybrid of warm and waterproof, town and country, smart and casual? Possibly. The internal insulator unzips to create two standalone jackets, the faux-fur hood zips on and off, and the whole thing is a) fully weatherproof and b) just as sweet-looking on Piccadilly as it is on Picws Du. NB: For some reason it’s hard to find on the Decathlon website; type ‘waterproof 3in1’ in the search bar. decathlon.co.uk
