What Our Gearhead(R) Experts Are Saying:"This short sleeve is the perfect balance of comfort and performance. The Knit_Flow fabric keeps air moving, dries super fast, and never clings. I wear it for everything-training runs, gym sessions, even travel."The best running gear is the kind you forget you're wearing. That's why we love the Salomon Shakeout Core Stlr T-Shirt. It's built with ultra-breathable Knit_Flow(TM) fabric that uses a 3D knit structure to increase airflow, regulate temperature, and feel smooth next to the skin. Whether it's a pre-dawn shakeout or a mid-day tempo, this tee moves with us and keeps distractions to a minimum. Flatlock seams prevent chafing through repetitive motion, while 2-way stretch ensures freedom to stride, sprint, and stretch. A regular fit adds room for movement without feeling baggy, and reflective details help keep us visible when the light's low. It's simple, lightweight, and built for motion-just how we like it.
