This piece is made from 100% cotton, a natural fiber that feels soft against the skin without stiffness or itch. The knit construction creates a natural air-insulating layer that helps retain body warmth, while the cotton itself allows air to pass through and wicks moisture away, so you stay warm without feeling clammy. The hood and ribbed cuffs and hem help reduce heat loss at the neck, shoulders, and waist. The fabric weighs 687g per piece, giving it a substantial, regular thickness that suits autumn and winter wear. The relaxed, loose fit with dropped shoulders allows easy movement without restriction, and the solid-color, minimalist design fits a casual, laid-back aesthetic that layers well over other pieces or wears simply on its own. The knit is fine-gauge, durable, and washable for easy care.
