Want a sure sign of warm weather? Suntanned pipes in a classic blowout shirt. This one combos beefed-up, layered appliqué graphics with the vintage cutoff sleeve style for retro style. The Copperblock Blowout is built from hearty cotton twill that’s prewashed to ditch the stiff new feeling. A snap chest pocket and embroidered felt patch finish this men’s sleeveless shirt.
