Lightweight sweater in the color light birch. This is a fully fashioned shortsleeve polo. It's knit with Wonder Yarn — the lightweight yarn that lives up to its name. This peachy soft yarn offers the all-season warmth of wool, without the wool. It’s made with LENZING™ ECOVERO™ Viscose — responsibly sourced wood-based fibres produced through a process that reduces impact on forests, biodiversity and water supply. This version is constructed using a Fine Rib stitch with thin, compact columns for comfortable widthwise stretch.
