"Women's On® 3"" Core Shorts: The On 3"" Core Shorts are lightweight women's running shorts built for warm-weather training when you want to move fast and stay cool. The 3"" inseam keeps coverage minimal and freedom of movement high, making these a natural reach for tempo runs, track sessions, or any day when heat is a factor. The integrated inner brief means you can skip the separate liner - support and comfort are already built in.The lightweight performance fabric promotes airflow so the shorts stay breathable even when the effort picks up. An elastic waistband with an adjustable drawcord lets you dial in the fit before you head out the door, and it stays put through the full run without needing attention. Storage pockets give you a place to stash keys or fuel so you're not carrying anything extra in your hands.Why Our Fit Experts Love It""I grabbed these for a hot morning run and barely noticed I was wearing them - that's the point, right?
