This is the Ultra-T. Made to withstand the most extreme conditions, it's the high-performance solution for your trail running goals. A lightweight, breathable panel at its back helps keeps distractions out and comfort in, while bonded seams reduce friction so you can speed through the trails and towards your goals. Engineered to go serious distances, the tee is also equipped with a small back pocket where you can keep your essentials. It works well on its own or under a vest to prepare you for whatever may come.
