You asked, we listened. We took our bestselling, technical Air Crew Tee and made a long-sleeved version. This style is made from our Midweight Air so it's a little more substantial and great for layering. Don't worry, it's still stretchy and incredibly breathable. Finally, a technical tee without the intense "athleisure" look. We took our insanely light and breathable Air fabric and made it slightly warmer for our outerwear styles like this. Don't worry, it's still incredibly comfortable and stretches just like the original. Adom is 6'2", wears a Medium, and is from Berlin. Oh Hallo!
