Guernsey Sweater NavyA traditional hand framed jumper from the British Channel Island of Guernsey. An authentic garment designed for seamen, who required a warm, hard wearing and comfortable item that would resist the sea spray. 100% wool. Guernsey's are made from worsted wool, whose longer, stronger fibres result in a tighter knit. This means the sweater will retain its shape and resist pilling. Properly cared for, a Guernsey can last a lifetime!
