This unisex sweater with a 1/2 zip is made from EKOALPAKA yarns - 100% British alpaca. It is soft and chunky and has been knitted in our design studio as two layered knit with a tough exterior in forest green alpaca and a soft underlayer in fawn natural alpaca. A must have for outdoor pursuits like hiking and walking. Alpaca is 3 times warmer than cashmere or merino. It will keep you warm and dry.
