A really good jumper is one of the most satisfying purchases you can make. The right weight, the right fit, the right wool or cotton or cashmere content. It keeps you warm without being bulky, it looks considered without requiring much thought, and a genuinely well made one lasts years and looks better for it. We’ve been pulling together the jumpers we actually rate. Not the ones that pill after three wears. The ones that hold their shape and their colour and continue to feel good every single time you put them on.
