What Our Gearhead(R) Experts Are Saying: "This long sleeve is my go-to for cool-weather runs and travel days. It's so light I forget I'm wearing it, and it keeps me dry even during tough efforts. The 37. 5 and Ionic+ tech really do their job-no stink, no sweat hang-up, and the bonded seams are smooth as it gets." For those early starts and shoulder-season sessions, we need layers that keep up. The Salomon Sense Aero GFX Long-Sleeve T-Shirt gives us featherlight performance in a coverage-forward silhouette, making it ideal for high-output runs and all-day wear. Built with Salomon's Knit_Flow(TM) fabric and 3D structure, it keeps airflow consistent and comfort dialed while thermoregulating 37. 5(R) technology and Ionic+(R) Botanical odor control maintain freshness no matter the mileage. The slim fit moves with us, the bonded seams eliminate friction, and reflective hits boost visibility when daylight's short. Finished with bold seasonal graphics inspired by global running culture, it's a long sleeve that works as hard as we do-with the tech to back it up.
