In a new direction for performance wear, Under Armour Japan launches UA WOOL, its first Merino wool collection designed for high-intensity training.
Reworking its trusted performance gear, Under Armour elevates a suite of training essentials with the natural benefits of Merino wool. Launching a six-piece capsule collection for running, long trail sessions and high-intensity gym training, UA WOOL merges the wool fibre’s natural comfort, breathability and technical strength with Under Armour’s expertise to craft gear that supports the body in motion.


Combining Under Armour’s original performance yarn technology with Merino wool, UA WOOL offers next-generation training gear with the best of wool’s natural functionality. With the wool fibre’s comfort and temperature-regulating properties and Under Armour’s material technology, athletes can train harder, stay comfortable in changing conditions and perform at their peak.
The collection features Wool Blend base- and mid-layers each carrying the Woolmark certification, signifying that garments have undergone rigorous quality testing.
Designed for everyday and professional athletes alike, the collection was put to the test by professional runner Haruka Koyama, trail runner Sena and football player Kei Chinen, showing why Merino wool, whether pure or blended, keeps pace with changing conditions through its natural dynamic breathability and comfort.
