Bamboo fabric boxers.
Bamboo fabric is a natural textile made from the pulp of the bamboo grass. Bamboo fabric has been growing in popularity because it has many unique properties and is more sustainable than most textile fibers. Bamboo fabric is light and strong, has excellent wicking properties, and is to some extent antibacterial. The use of bamboo fiber for clothing was a 20th century development, pioneered by several Chinese corporations.
Bamboo fiber resembles cotton in its unspun form, a puffball of light, airy fibers. Bamboo fabric is very soft and can be worn directly next to the skin.
