Started in 2014 by a group of friends who wanted to manufacture no-fuss, timeless core pieces that can team effortlessly with everything. Designed in London and produced in Mongolia, where all the best cashmere is made, Jumper 1234 supports the lives of the nomadic herdsmen of Mongolia and their families, who are passionate about their cashmere. Made by artisans who have years of experience knitting cashmere, their pieces are guaranteed to retain their look and feel for years to come.
