What Our Gearhead® Experts Are Saying:"I’ve put the Distance Tech Tee through everything—long runs, travel, even gym sessions. It’s incredibly light, dries fast, and never feels clingy, even when it’s humid. The fabric is soft enough for all-day wear, and the flatlock seams prevent any chafing. It’s my go-to for training days and casual miles alike."We pull on the Black Diamond Distance Tech T-Shirt when early starts and long days on the trail call for breathable performance. Designed to move with us mile after mile, this lightweight running shirt delivers the ideal balance of comfort and technical efficiency. The quick-drying polyester jersey fabric wicks moisture to keep us cool, while an anti-odor finish helps us stay fresh through back-to-back runs or travel days. Flatlock seams eliminate chafing during extended wear, and a reflective logo boosts visibility when we’re finishing miles under fading light. Lightweight, packable, and built for motion, the Distance Tech Tee is the kind of top that earns a permanent spot in our running rotation.
