We asked Mr.Tortamano , Industrial Technology Manager of Santista Textil, a major spinning company in Brazil, to wear our sample socks made of VORTEX yarn (an acrylic-cotton blend). He goes walking in the morning four times per week wearing the socks, and was satisfied with them because the VORTEX-made socks were more comfortable than any products he wore before, while repeating washing it never caused pilling. The socks have been worn so long that a hole has formed but this is after more than four years use! Mr. Tortamano praises this product saying “I would buy these socks even if the price is higher than other socks. These socks are wonderful and never went out of shape or had pilling.” In Brazil VORTEX yarn is often chosen for uniforms, tablecloths, and bed linens because these goods require durability.
