Versatile, warm and lightweight, the Down Sweater Hoody from Patagonia is everything you want from a down mid-layer. As the name suggests, it's somewhere between a jumper and a jacket – ideal for wearing on its own or layering under a waterproof shell. The 1.20oz 20-denier ripstop shell fabric keeps the wind out and the down in (because no-one wants to go around shedding feathers) – and it's got a PFC-free water-repellent coating. What's more, it's even made from recycled fishing nets to help reduce plastic pollution.
