Weighing in at just 125 grams and featuring a two-density knit construction with strategically placed ventilation zones, this men's trail running shirt is for those who want performance. With no annoying seams to avoid chafing, it has a close-fitting cut with a round neck and short sleeves that can easily be worn with a trail running backpack. Its highly breathable DRYNAMIC KNIT fabric stretches to follow your movements and is abrasion resistant. An added bonus is the reflective logo that optimizes your visibility in low light conditions.
