What Our Gearhead® Experts Are Saying: "This long-sleeve is in my year-round kit. The Knit_Flow fabric keeps things breathable on warmer days, and the added sleeve coverage is perfect when temps drop or I want sun protection. It fits like a performance shirt should—clean and comfortable." When conditions call for more coverage without sacrificing breathability, we reach for the Salomon Shkout Core Long-Sleeve T-Shirt. Built with advanced Knit_Flow™ fabric, it delivers lightweight airflow, next-to-skin softness, and just the right amount of stretch for high-movement training days. Flatlock seams eliminate friction through long runs or layered missions, while reflective branding ensures we're seen when light is low. Whether we’re logging shoulder-season trail miles or shielding from the sun during a high desert push, this long-sleeve keeps us cool, covered, and moving free.
