This pool floatie of a jacket from London designer Christopher Raeburn bridges concept and comfort. Not only does it bring back memories of childhood buoyancy, but it’s surprisingly warm and super lightweight, too, as it’s made of little more than latex and air. The hoodie alone could double as a cushion. Plus, the blow valves are exposed for easy re-inflation.

Fellow straphangers on the subway won’t take kindly to the jacket, but if even they spitefully poke a hole in the latex, worry not, for it even comes with a puncture repair kit.

£949 at Christopher Raeburn
