What Our Gearhead(R) Experts Are Saying: "This shirt is a staple in my training lineup. It's ridiculously light, dries fast, and never gets soggy-even during brutal workouts. It fits close without feeling tight and doesn't ride up when I move. Whether I'm running or lifting, it's always in rotation."Whether we're stacking miles, hammering hill sprints, or dialing in strength work, the Ten Thousand Lightweight Short-Sleeve Shirt delivers the kind of performance comfort we barely notice-because it's working that well. Ultralight and moisture-wicking, it's built to breathe through the sweatiest training days without clinging or holding onto odor. The tailored fit and stretch fabric move with us through every push-up, pull-up, and stride, while flatlock seams keep hot spots and chafing at bay. With Polygiene(R) anti-odor tech and an athlete-tested design, it's the shirt we reach for when we know we're going to work hard.
