We designed the Essential Bird line to be your perennial favorite, reach-for-every day running gear, which is why we're stoked to introduce a full-zip jacket to the lineup. Made from the soft but compressive fabric the rest of the Essential Bird line boasts, its semi-fitted silhouette is perfect as a mid-layer when the cold really takes hold. The wide, tall collar makes a statement and the thumbholes and zippered pockets give it even more opportunities to work hard for you mile after mile.
