These are modern semi-open fit technical pants designed for versatile everyday and light outdoor use. Featuring a streamlined silhouette with subtle functional details—including adjustable cuffs, reinforced stitching at stress points, and a relaxed yet tapered leg cut—the pants offer both comfort and durability. The fabric appears to be a lightweight synthetic or blended technical material, suitable for transitional seasons, with breathability and slight stretch for mobility. The '半开' (semi-open) designation suggests a contemporary design with partial side zippers or open hems for styling flexibility. Ideal for streetwear, casual outings, urban exploration, or light hiking. The clean black color ensures easy pairing with any top, while the tailored waistband with drawstring allows for a customizable fit. Sizing chart provided includes M–XXXL with measurements in cm; note that manual measurement may have ±3cm variance. No visible logos or branding elements present, indicating a generic or unbranded product focused on utility and minimalist aesthetics.
