Julie Sinden combines function and fashion to keep you warm all winter long. All products are made from 100% merino wool, which is first knit, then felted. It's just like when you shrink your wool sweater in the washing machine. The resulting fabric is boiled wool, which is incredibly warm, water-resistant, and windproof. The perfect material for a Canadian winter. But because it's merino wool, it's also super soft and breathable.
