What Our Gearhead(R) Experts Are Saying:"I've worn the Natural Flow Tank Top through plenty of sweaty studio sessions, and the hemp blend fabric never holds onto odor the way a lot of gym shirts do. The side seam venting makes a real difference once the class heats up."A good studio session asks for gear that keeps up without getting in the way, and the Natural Flow Tank Top from prAna does exactly that. Pull it on before class, roll into your first sun salutation, and let the lightweight hemp blend move with every stretch. The recycled polyester and hemp fabric wicks moisture and resists odor through a full sweat session, while side seam venting and forward side seams keep airflow moving where it matters most. Flat lock seams stay smooth against the skin, whether you're holding a pose or heading out the studio door.
