YBamboo - Clothing for Men, Women, & the Earth. YBamboo? Because it’s an environmentally friendly, high performance fabric! Bamboo is fast growing, (up to 1 ft. per day), has a natural sheen and won’t fade like cotton. It absorbs moisture like the best athletic wear, is naturally anti-microbial and odor resistant. Though you can throw it in the washer and dryer, it still feels like cashmere and drapes like silk.
