Fabric: 93.5% Polyester, 6.5% Nylon The piece is made from a knit fabric of 93.5% polyester and 6.5% nylon, with a marled fleece texture that gives it a soft, fuzzy handfeel. The fabric weighs 630g, a substantial weight that provides warmth and a stronger sense of envelopment while the relaxed, old-money aesthetic and American casual style keep the look easy and laid-back. The seagull collar opens naturally to frame the neck and shoulders, and the ribbed cuffs help reduce drafts at the sleeves and keep them from riding up. The materials suit the piece's relaxed, casual character and its use across everyday wear, commuting, the office, campus, dates, gatherings, and travel in autumn. The knit construction and 630g weight make it a warm layer for the season, while the soft fleece-like surface keeps it comfortable against the skin.
