The Best Socks Made From Bamboo Bamboo Socks For Men and Women Bamboo viscose fibers are derived from one of the most ecologically friendly grasses on our planet, making it an attractive alternative to cotton and petroleum-based fibers. Bamboo requires no irrigation as it thrives under natural rainfall and requires no pesticides or fertilizers. Once mature, it can grow up to 47-inches in a single day and holds the record as the world's fastest-growing plant. Bamboo does not need to be re-planted after harvest as it is a grass and grows back from the cut. A stand of bamboo creates 35% more oxygen than an equivalent stand of trees while absorbing 5-times the greenhouse gases. With so many uses, there is little to no waste with harvested bamboo. The moisture management and breathability of these fibers remove sweat and moisture away from the skin where it can evaporate to help keep your skin dry and clean. Odor-causing germs can not grow without moisture, and the evaporation process helps keep your skin cooler in the summer and warmer in the winter. The next to skin smoothness reduces friction and helps prevent blisters in a sock. These performance attributes make these yarns ideal for socks. Blister Free Promise Products designated with the Blister-Free Promise seal are made with yarn that naturally removes moisture and friction (caused by moisture). We offer a life-time blister-free promise that those products will not contribute to the formation of foot blisters. One World! One Sock.
