The most obvious answer must be thicker. Kayhoma thigh high socks are indeed more than 50% thicker than ordinary thigh high socks. But in the beginning, the thick was not for keep warm, but to increase the stability and longevity of thigh high socks. Obviously, thicker thigh high socks are not easy to deform and have a longer service life. At the same time, their warmth retention performance has also increased.
Kayhoma thigh high socks are also very long. They are usually 28-29 inches tall, so they can easily reach the middle of the thigh. They can cover the gap between the skirt and the boots, so even in winter, they can also support the switch between indoor and outdoor.
The most important reason is not actually thick and extra long, but the underwear-grade cotton yarn used in Kayhoma thigh high socks. These cotton yarns are completely different from ordinary cotton yarns, they are all selected. The fine hairs on the cotton yarn are very long and very soft. All of them are denser than ordinary cotton materials, they have better resistance to wind, and easier to maintain the temperature of the thighs.
