Lighter. Faster. Same Aeria Fortis DNA.
Our Aeria Fortis Race Shorts are 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. A durable silicone patch detail adds a refined technical finish built to withstand the demands of everyday training.
A built-in black stretch brief liner moves with you, providing comfortable coverage while helping reduce chafing and irritation as you run.
A secure zipped back pocket fits an iPhone Pro Max and two energy gels, keeping your essentials locked in and within reach.
From daily mileage to race day, the Aeria Fortis is built to move fast and go the distance.
