Charles TyrwhittThis cardigan is made from 100% extra fine merino wool in a jersey knit, to a simple and elegant shape. The merino fibers make it lightweight and soft, yet offer good insulation in cold weather, and the piece has been garment washed for extra softness. Shaped to a V neck with a six button fastening and ribbed hem and cuffs, this is a straightforward and failsafe cardigan; a suitable middle layer for both casual and formal looks.
