100% Merino wool gives the piece its soft, warm handfeel and natural breathability, making it well suited to relaxed, casual layering through autumn and winter. The fabric weighs 887g per piece, and the loose, oversized silhouette supports the easy, laid-back styling the piece is designed for. The collar is made of 100% cotton, while the ribbed collar edge, cuffs, hem and side pockets are finished with ribbed detailing that helps the piece hold its shape over time.
