The Ultimate Guide to Cotton Underwear vs. Silk Underwear

In the clothing world—and especially in the underwear world—the cotton versus silk debate is a big one. What is better cotton underwear or silk underwear? Keep reading to find out- 

  • Which is better for your body?
  • Which is better for the heat? The cold?
  • Which is the more comfortable underwear option?!
  • Is cotton or silk underwear healthier? 

Well, picture us holding a giant gavel because we’re about to lay down the law on what’s better when it comes to silk versus cotton.

What is cotton underwear?

First, let’s all agree on what we’re actually talking about. 

According to Merriam-Webster, cotton is a soft usually white fibrous substance composed of the hairs surrounding the seeds of various erect freely branching tropical plants. (P.S. We also just learned that “cottoned” also means “to come to understand,” as in, we’ve cottoned on to the fact that it’s not just about fabric. Who knew?)

Mood Fabrics describes cotton as being known for its absorbent qualities, noting that most cotton retains 24-27 times its own weight in water. While this is absorbent for a natural fiber, and a solid choice for underwear, we can expect more from silk.

What is silk underwear?

Like cotton, silk is a natural fiber. More specifically, it’s a “fine continuous protein fiber produced by various insect larvae usually for cocoons.” 

Its history, which dates back to the 27th century BC in China, shows that it has almost always been considered a luxury item. History of Clothing says it became very popular among high society, and that laws were made to regulate and limit the use of silk to the members of the imperial family.

Fast forward to today, and it’s what we use to make Uwila Warrior Soft Silk underwear and silk camisoles.

Along with many other manufacturers, we’ve found that cotton is too slow to dry, which can lead to yeast infections and other discomforts and aggravations. You may have read about those in our other blog post on sweat-wicking underwear. These silk panties are the healthiest option you can pick. 

Unlike cotton, silk can hold 40% of its weight in moisture before even feeling wet. It’s also sweat-wicking, super soft, and deliciously comfortable. Our CEO Lisa Mullan adds, “The quick-drying nature of silks make them perfect for traveling—long nights and long car rides—they can be washed that night, and be clean and ready for the next day’s adventures.”
