Constructed using worsted wool twill stretch. Worsted wool is a finely woven wool material that is woven with fine yarn, which has a glossy and supple texture and is mainly used for suits, and is made from yarn spun with "combed" wool, which is made from carefully selected long and thin wool with little fuzz. This Material is printed with a "wind-running pattern" using pigment and the details include a boat neck and elasticated sleeve to make this an incredibly easy piece to pull on and off.
