The piece is made from a fabric blend of 63% Polyester, 25% Rayon, 6% Spandex, and 6% Tencel, giving it a denim-look slub texture with fine vertical grain that adds visual depth. This composition supports a standard fit and a business-style aesthetic suited to interviews, daily wear, commuting, and business occasions, while the wind-resistant function makes it practical for autumn 2026 layering. The fabric is a single outer material with no separate lining or filling listed.
