On Running Women’s Active Tank | Sea Tops

A versatile, ventilated open-back tank top.

Technology | Stretch, Move, Explore

The Active Tank is designed to keep up with any on-the-go lifestyle. The open back design works with the fast-drying fabric and extreme ventilation to keep you feeling fresh, even on warmer, more active days.

Materials | Comfort in Movement

Made from an anti-odor lyocell/elastane blend, the Active Tank combines soft-touch materials with a cut to keep you fresh and comfortable all day. Gently hugging but stretchable enough for any workout. Be free to explore your full range of motion.

Design | Just like Breathing

Swiss-engineered for comfort and breathability, the Active Tank’s open back design and deep shoulder cut accelerate airflow. The high neckline and strategic double hemming keep the shirt in place but never restrict your natural range of movement.
