The difference between Kabala silk underwear and KingStyle: 1) Fabric, Kabala is the best underwear fabric in Modal, which is soft and comfortable and has the texture of silk. KS is made of stretch cotton, which is uncomfortable. 2) Kabala scrotum bag is made of silk protein fiber, which is skin-friendly, breathable and heat-dissipating, and keeps the local temperature at 2-3C, which is beneficial to men's health. KS scrotum bag is made of elastic cotton, and scrotum bag is made of mesh elastic cotton, so the ventilation and heat dissipation effect is definitely not as good as silk. 3) Kabala has a health-care type specially designed for patients with varicocele, which lifts the scrotum, promotes venous return, breathes air and dissipates heat, which is beneficial to semen quality. On the other hand, KS has no medical care model specially designed for patients with varicocele. Search for U-shaped underwear or silk bags on Taobao.
