Cons

  • Bamboo is highly absorbent. It holds much more water and sweat than cotton. This may encourage microbial growth.

Combed Cotton

Some people prefer combed cotton underwear. It has the benefits of regular cotton. But it undergoes a process to make it extremely soft and lustrous.

Pros

  • Combed cotton lacks any impurities and is a softer version of regular cotton. It’s also stronger. Combing the cotton gets rid of short fibers that are prone to breakage.
  • This allows the straightened fibers to join together more tightly. As a result, less fraying and unraveling occurs. Combed cotton is more luxurious than regular cotton for this reason.

Ring-spun cotton has a more luxurious feel due to its fine and extremely soft texture. Reproduced on a ring frame equipment, it has a stronger weave than regular cotton fabric.
