There are many options for fabrics when it comes to men’s boxers. You’ve got materials like cotton, nylon, silk, Spandex, and much more. Deciding what fabric is best is based primarily on personal taste and what you feel is most comfortable. Generally speaking, silk boxers tend to be more lightweight and feel cooler when you’re wearing them, so if you’re in a warm climate, you may consider silk or cotton boxers. If you’re somewhere colder, wool boxers may be the way to go.
