This T-shirt is made from Harlem 2.0 Micro-fresh polyester jersey fabric with antimicrobial properties so it keeps you feeling fresh for longer. The compact microstructure of the fabric reduces contact points on the skin so the T-shirt dries quickly and is comfortable to wear when trekking in the mountains or going on a short hike on a summer evening. Made for hot weather, the men's World 2 T-shirt effectively wicks away moisture as you sweat to keep you feeling cool and comfortable from the first step to the last.
