Designed for high-output pursuits in warm conditions, the Mammut Women’s Aenergy FL Tank Top is the ultimate combination of technical precision and featherlight performance. Crafted for runners, hikers, and climbers who demand peak breathability, this racerback tank delivers maximum airflow and comfort with every move.
Strategically placed mesh panels under the arms and across the back provide targeted ventilation exactly where you need it, while smooth, offset merrow stitching minimizes friction on the skin—making it ideal for long days on the trail or training sessions that push your limits. Constructed entirely from recycled polyester, it not only supports sustainable performance but also features HeiQ Fresh bio-based odor control technology to keep you feeling fresh, mile after mile.
With its moisture-wicking and quick-drying fabric, this tank actively manages sweat to maintain a dry, comfortable microclimate next to the skin. Reflective detailing ensures added visibility during early morning starts or late-evening runs. At just 62 grams, it’s the lightest base layer in Mammut’s lineup—engineered for athletes who move fast and stay focused.
