Pantalón de running On Core mujer - negro, talla M

Hit the pavement, the gym, or the trail in the On Women's Core Running Pants. Cut for an athletic fit and built from a technical stretch fabric made with 86% recycled polyester, these pants move with you through every stride, squat, and stretch. The elastic waistband with adjustable drawstring lets you dial in the fit, while the tapered leg keeps the silhouette streamlined and free of excess fabric. A zippered side pocket secures your keys or card, and a second open pocket gives you quick access to your phone or gels. Reflective details help you stay visible when your run stretches into low light, and the moisture-wicking, quick-drying fabric keeps you dry from warm-up to cool-down.

Good to know

The Core Pants are designed with sustainability in mind, using recycled materials without compromising performance. The pull-on closure means no zippers or buttons to chafe, and the tapered leg works well with both running shoes and casual sneakers. For best results, machine wash cold and lay flat or tumble dry low to maintain the fabric's stretch and shape.
