For the Aertex-ignorant, it’s the revolutionary ‘Cellular’ fabric – invented in 1888 – that keeps you cool during summer, but traps heat in the winter. They even provided sweat-proof uniforms for the Desert Rats during World War 2.

Best known for their short-sleeved shirts, vests and underwear, Aertex have relaunched with a heritage-inspired shirt-and-top collection that’s very Ralph-meets-Ben-meets-Gabicci. Shirts come in granddad, preppy button-down, military-inspired and Goodfellas- mobster flavours, as do many of the other key pieces in the collection. As Sir Paul Smith so rightly put it, Aertex is simply ‘very English’.
