All natural doesn't exactly sounds tough-as-nails, but it turns out that hemp is an exception to the rule. It naturally filters UV light to protect against harsh sun, has 4x the durability and strength of regularly-treated cotton, and resists bacteria and odors. Not to mention that growing hemp uses a fraction of the water and energy it takes to produce other "natural" materials, and its breathability and soft coziness are unmatched. So, it's no wonder that hemp is quickly becoming a climber's dream fabric that packs a one-two, performance-while-doing-good feel from bouldering to boardroom.
