This cardigan is knit from a blend of merino, baby alpaca, and other fibers for an incredibly soft and gently fuzzy look and feel. It has a substantial 7-gauge weight — in other words, perfect for wearing it on its own now and layering under your outerwear deep into winter. Quality details include genuine horn buttons and tonally-contrasting merino wool edging at the placket, collar and hand pockets. By the way, if you're not feeling the full coat and tie thing when you next head into the office, this looks quite sharp with a knit tie.
