Brad from San Diego, CA: I just went shopping for new pairs of underwear after I finished cleaning out my underwear drawer. While I was looking for new styles for the spring season, I came across a few products made from rayon—or as the tag noted, “produced from a bamboo fiber.” What are the benefits of this fabric?

The Underwear Expert: Brad, we’re glad you pointed this out. Rayon underwear is a great choice to have for your collection, and we’re sure you will love its form-fitting benefits.

Rayon is a manufactured fiber made from regenerated cellulose derived from plant materials such as bamboo. Rayon fabrics are very soft and breathable. As one of the world’s oldest manufactured fibers, rayon is used for a variety of textiles including underwear. Most underwear manufacturers mix with rayon with other fabric blends to achieve a stretchable fit. Rayon underwear is great to wear during the warmer weather since it provides a silk-like feel.

Check out our picks of the top choices of rayon underwear, which include a brief, boxer brief and trunk, and tell us which one strikes your fancy!

This brief is made from a fabric combination of 70% rayon and 30% cotton, which gives a special transmission of comfort.

The brand also added season colors of green flash, blue stone, clearwater teal and grenade green to the range. S-XL.
