ON RUNNING WOMEN'S CORE-T

GURU TIP: This tee has a tailored fit that sits close to the body. If you prefer a more relaxed or oversized vibe, consider sizing up.

TECH TIP: The On Core-T is a lightweight, do-it-all essential crafted with performance cotton and just the right amount of stretch. Designed with a breathable blend of organic cotton and elastane, this tee feels soft against the skin while holding its shape through repeated wear. The clean, minimal design pairs easily with anything — from run tights to recovery joggers — and the fit is flattering without being clingy.

BUY THIS TEE IF: You want a premium everyday shirt that effortlessly transitions from warmups to wind-downs, with comfort that doesn’t compromise on style.

DON’T BUY THIS TEE IF: You’re looking for a tech tee built for high-sweat, high-mileage days — this one’s more for lifestyle and light activity than full-on workouts.
