The Hyannis sits at the cleaner, more refined end of our polo sweater line-up — slimmer than its sportier Rally counterpart, with banded sleeves and a banded hem that give it a subtle mid-century feel. Think 1960s jazz or a long weekend at the Kennedy Compound. You choose the reference. This particular knit, a textured cotton/linen blend, works just as well with casual trousers as it does with a pair of shorts. It's finished with a clean French placket and our go-to Trocas shell buttons.
