These midweight long underwear bottoms combine bamboo-derived with polyester for an environmentally friendly, high-performance base layer.
- Polyester and bamboo-derived charcoal polyester blend for moisture-, odor- and UV-management using natural means instead of chemicals
- Polyester yarns are embedded with charcoal from carbonized bamboo; the highly porous nature of carbon helps wick and disperse moisture, drying quickly
- Bamboo charcoal naturally removes odor and particles from fabric—just like your water filter— and won't wash out
- Naturally UV-resistant fabric with a UPF 50+ rating shields skin from the sun's harmful ultraviolet rays
- Bamboo is a highly renewable resource that is easily grown without fertilizers and pesticides, resulting in far less impact on the environment
- Elastic waistband and a gusseted crotch allow unrestricted range of motion
- Flatseam construction is soft and nonchafing next to skin
- Machine washable
