This is a gently used Athleta Ascent tank in black, size medium. I replaced it with a large, I love this line. I have the long sleeves and some tanks, unfortunately, Athleta is discontinuing this line. It is a great layering piece or good alone. It is not for working out, it is for every day where. But I do wear my long sleeves hiking because the fabric is on the warmer side. Smoke and pet free home.
