JBS of Denmark bamboo tights for men are designed with the focus on optimal comfort, so you can feel relaxed and at ease when you're wearing them. We call it: Designed to relax. You can forget all about irritating labels. The label is welded to the edge of the underpants, and the washing instructions are printed on the fabric. This ensures the labels don't irritate the skin. This product is FSC-certified. The FSC-certification guarantees that the bamboo is sourced responsibly, meaning that the bamboo originates from a plantation where no more bamboo is felled than the plantation itself can reproduce. In addition, the certification ensures that animals and plant life are protected and that there are proper conditions for the people working with the cultivation of the bamboo.
