Jumper 1234 is a British cashmere knitwear brand founded in 2014 by longtime friends Jane Wilson and Denise Tavernier, whose 25-year friendship and shared passion for cashmere created this distinctive label. Born from a genuine love of knitwear and infused with humor, the brand specializes in creating timeless, no-fuss cashmere pieces that combine contemporary design with playful vibrancy. All design work takes place in London, while production is based in Mongolia, sourcing raw cashmere directly from nomadic herdsmen to support their livelihoods. The brand is committed to sustainability, using naturally sustainable cashmere that's ethically sourced and crafted by skilled artisans with years of experience. Originally focused on women's knitwear, Jumper 1234 has expanded into menswear, maintaining their signature approach of creating effortless, colorful pieces designed to last for years. Their machine-washable cashmere represents a perfect blend of British design sensibility and Mongolian craftsmanship.
