When it comes to knitwear, John Smedley is second to none - it's been operating out of its Derbyshire mill since 1784, making it the oldest factory in the world. This zip-up cardigan is handmade from extra fine merino wool spun in a textural chain stitch. It'll work in place of a jacket during the warm part of the year, and as an insulating mid-layer the rest of it.
