- Regular in size The package contains 2 pairs of boxer shorts. Underpants…Which are not made of bamboo or cotton! No, they're made of something we think is far better! Namely the softest Micro-Modal. And what is that? It is an extremely soft and fine material made from wood fibers from sustainable forestry. Micro-modal gives you a product that is both incredibly soft, but also wonderfully light and durable. The material is made by the Austrian manufacturer Lenzing, which is known for its innovative and green initiatives in materials development.
