Re-introducing the pinnacle of shirt engineering. We've revamped the super-versatile Secret Wash shirt with premium 100 percent cotton 100s two-ply yarns, plus an improved fit. "100s" refers to a finer yarn size, and "two-ply" means two yarns are twisted together to make a single thread. The result is smoother, stronger fabric. We also use our (proprietary) multistep wash process to achieve a soft, broken-in feel from day one. Long story short: The customer favorite since 2005 is now better than ever. 100% cotton. Machine wash. Imported.
