The Relentless Forward Progress Unisex ¾ Sleeve Shirt is a casual unisex raglan, tri-blend shirt by Next Level made from a blend of 50% polyester, 25% combed ringspun cotton, and 20% rayon jersey in the vintage black and heather white colors. The fabric is pre-laundered for reduced shrinkage. The fit is adult unisex. The fit tends to run standard to a bit on the small side, so if you’re in between sizes, size up. iRunFar’s Relentless Forward Progress graphic is screen printed in large format across the chest. The Relentless Forward Progress graphic was designed by runner and artist Alessandro Locatelli.
