The weight of a towel can be a great indicator of quality and performance. Typically, towel density is measured in grams per square meter (GSM) and ranges from 300 to 900 GSM. Towels with 600 GSM - like this Egyptian Cotton Towel Set - offer a more luxurious, spa-like experience. This medium-density towel will soak up water fast for noticeable absorbency, and dry quickly for a fresh feeling with each use. Considered best in class when it comes to high-quality cotton, Egyptian cotton offers a sought-after combination of superior strength and luxurious softness. It makes a great choice for bath towels because of its high absorbency and breathability, which means water gets wicked away quickly and air can circulate for faster drying. Egyptian cotton grows in the warm climate of Egypt and features extra-long durable fibers that give towels a beautiful texture and long-lasting strength. Ringspun yarn repeatedly twists together strands of long and short fiber to the point where they become an extremely thin, tightly woven rope of fiber. The twisting process causes short fiber hairs to stick out, creating a noticeably soft hand feel and, overall, an ultra-smooth yarn with superior strength. Compared to combed yarn, ringspun yarn typically offers a sleeker finish for a more polished appearance. An Amazon Brand.
