Engineered for the Unrelenting Runner and Triathlete

Under Armour was born from a simple mission: to make all athletes better through passion, design, and the relentless pursuit of innovation. For the dedicated runner and the determined triathlete, this translates into high-performance gear that works as hard as you do, from the first mile of training to the final push across the finish line. At runnerinn, we are proud to present a curated collection of Under Armour apparel designed to empower your performance, with a special focus on their exceptional range of running jackets—your essential shield against the elements.

A runner´s greatest opponent is often not the distance, but the conditions. Under Armour understands this challenge intimately, which is why their running jackets are more than just an outer layer; they are a piece of performance equipment. Don´t let the weather dictate your training schedule. Featuring the revolutionary UA Storm technology, many of these jackets offer superior water resistance without sacrificing an ounce of breathability. This means rain beads up and rolls right off, keeping you dry and comfortable, not clammy and overheated, during those wet-weather runs. You can maintain your focus and form, knowing you´re protected from the downpour.

When the temperature drops and the wind howls, turn to jackets engineered with ColdGear® technology. These thermal layers provide incredible warmth in a surprisingly lightweight package, trapping body heat while still wicking sweat away from your skin. The result is a perfect microclimate that keeps your muscles warm and ready, allowing you to focus on your pace, not the biting chill. For the triathlete, this means a reliable piece of gear for those cold morning bike sessions or pre-race warm-ups.

Beyond core technology, every detail in an Under Armour running jacket is designed with the athlete in mind. Discover ultra-lightweight windbreakers that are easily packable, perfect for stashing in a race belt or pack for unpredictable mountain weather or long trail runs. Secure zip pockets keep your gels, keys, and phone safe, while strategically placed ventilation and mesh panels ensure you don´t overheat as you pick up the pace. For those early morning or late-night sessions, visibility is paramount. Many Under Armour jackets incorporate 360-degree reflectivity, with reflective logos and details that catch the light, ensuring you stay seen and safe on the road.

Complete your high-performance kit here at runnerinn. Pair your perfect jacket with Under Armour´s acclaimed running shoes, supportive compression tights, and moisture-wicking HeatGear® tops to build a complete system engineered for peak performance. Under Armour isn´t just apparel; it´s the confidence to push through that extra mile and to conquer the swim, bike, and run.
