Extended information:

The fabrics of men's underwear include pure cotton, modal, bamboo fiber, Lycra, nylon, Coolmax (respiratory fiber), MERYL, etc.

Pure cotton fabric: Underwear made of pure cotton fabric has strong hygroscopicity but weak moisture drainage (not easy to dry). If the skin is exposed to wet clothes for a long time, it is prone to redness, itching, prickly heat or scrotum damage. Eczema, dermatitis, etc.

Therefore, if you want to wear cotton underwear, you should ensure that the underwear is dry. People who sweat easily and men who often drive are not suitable for wearing underwear with excessive cotton content.

At the same time, the elasticity of cotton is weak, and the fit of pure cotton underwear will be greatly affected (improper wearing can easily affect the normal development of adolescent reproductive organs), so cotton underwear should add 5 to 10% spandex. (Top spandex such as DuPont's "Lycra") is used as an auxiliary material to improve the elasticity of underwear and enhance the fit.

Davidarchy men's underwear experts recommend that consumers with extremely sensitive skin and low sweating choose combed cotton underwear containing spandex.

Tactel (nylon 66): Tactel

It is a high-quality nylon fiber produced by DuPont in the United States, referred to as nylon.

Nylon makes the fabric soft and comfortable, and its good hygroscopicity can balance the humidity difference between the air and the body, thereby reducing

the pressure on the body and having an adjustment effect. Extremely lightweight and easy to maintain. It is machine washable and dries three times faster than cotton. It only requires light ironing or no ironing. It is not easily deformed and has significant anti-wrinkle ability.

Modal fabric: "Modal" is actually the brand name of the fabric, which is a "regenerated cellulose" fiber. Regenerated cellulose fiber is softer, stronger and tougher than other fabrics, and has significantly higher moisture absorption and perspiration capabilities than pure cotton products.
