Navy Core Base Layer Long Sleeve

The Women’s Core Base Layer Long Sleeve is the kind of piece you’ll reach for on repeat—whether you’re schooling at home, heading to a lesson, or layering up for early mornings at the stables.

Made from a super soft, four-way stretch sports fabric, it’s sweat-wicking and designed to move with you without losing shape. The fit is next-level thanks to a sculpted 3D-created pattern, plus shape-retainment technologies that help it stay looking sharp ride after ride.

For comfort where it matters most, it features laser-cut air vents at the sides, back, and underarms to boost airflow, and an extended zip for a more casual, easy-to-wear look (and quick temperature control). Finished with Core AD branding on the front, arm, and back.
