Our favorite gear is the gear that we forget we're wearing. No itching, no tugging, no chafing seams. Designed By Women, For Women, Oiselle apparel is tested by real runners in all types of weather. And in this case? We want the only thing you notice about the Essential Bird Long Sleeve to be the brand-new selection of so-you graphics that we're offering for a limited time. It's breathable while still protecting you from the elements, it features a Watch Window and thumbholes for on-the-go comfort and efficiency, and its relaxed fit moves with you as you run, no matter your pace. It's time to show off what you're made of.
