Our best-selling zip neck jumper is made from pure Yak yarn which is sourced from Tibet and spun in Inner Mongolia. Because of its beautiful colour the yarn is left undyed; we have used the light brown marl for the main jumper colour with a darker yarn inside the neck opening. Yak wool is an eco-friendly product, hypoallergenic and is just as soft as cashmere - it is also very breathable and is odourless! Further information on all our fibres can be found on our Yarns page. YKK metal zip with faux leather facing and a 'Misty' zip pull Knitted in a chunky 7-gauge knit 100% sustainable yak For a relaxed fit we suggest you order up a size.
