85% wool, 10% polyester, 5% polyamide. Knitted fabric. ¼ button fastening. Ribbed collar cuffs and hem. Buttoned brand patch. Regular fit. Who could have come up with this Button Quarter Knit other than Stone Island themselves. This dab slab is made from the dangerously toasty benefits of wool, polyester and nylon, and, alongside a handful of classy buttons, form a garb worth of shedding a little tear over. yes, it really is that good.
