Arc'teryx's pinnacle trail running shirt, the Norvan Downword is made to go far. Its hybrid construction combines soft, high-performance Phasic FL fabric with ultralight Delta mesh on the back for improved airflow. Merrow seams and laminated finishes in key areas minimize chafe, the design rides comfortably under a hydration vest, and the patterning removes restriction. And - for long mountain runs that push into the night - a large reflective logo improves visibility. Machine washable. Our model is 6'2" with a 37" chest and wears a size M.
