Lighter. Faster. Same Aeria Fortis DNA.
Our Aeria Fortis Race Tank is back, now upgraded with an even lighter recycled polyester fabric while retaining the seamless construction you know and love.
Built for performance, the new Fortis delivers the same durability, breathability and ultra-light comfort in a clean, distraction-free silhouette — now with even less weight and improved airflow to keep you cool when the effort picks up.
Engineered without side slits for a streamlined fit, the tank is finished with a durable silicone chest patch for a refined technical detail designed to withstand the demands of everyday training.
From daily sessions to race day, the Aeria Fortis Race Tank is built to keep you light, cool and focused.
