Details on the Aritzia website: Beloved for its cocoon-like feel and perfect slouch, this is a turtleneck sweater with dropped shoulders, a relaxed silhouette and fully fashioned construction. It’s knit with Embrace Merino™ — extra-fine 100% merino wool yarn coveted for its natural warmth and super soft feel. We source ours from a premium Italian mill. This version is constructed using a Half Cardigan stitch with vertical ribs for a textural look and feel.
