We're all about the smooth comfort and effortless style of the Oiselle Altitude Long-Sleeve Top. Made with Arque Nyelle Seamless fabric, this top wicks moisture and resists odors, keeping us fresh and comfortable no matter how many miles we're running. Its relaxed, boxy fit lets us move freely, while the signature bird graphic adds a touch of flair to our workout look. This is our go-to long sleeve for those who want a seamless, breathable layer that moves with them every step of the way.
