Best Men's Sustainable Underwear

Bamboo Underwear

Bamboo is a super renewable material. It's thermo-regulating, meaning it will keep you cool in summer and warm in winter, and is moisture-wicking and antibacterial.

TENCEL™ (Tree) Underwear

Also known as lyocell, made from sustainably sourced eucalyptus using an award-winning closed-loop process. It's moisture absorbent, antibacterial, breathable and extremely soft.

Organic Cotton Underwear

Organic cotton works in harmony with nature. It combats climate change, saves and protects water, doesn't use pesticides or fertilisers, and gives control to farmers.

Hemp Underwear

Natural and moisture-wicking, odour resistant, lightweight and breathable. Hemp is incredibly durable and helps to  fight global warming by absorbing 4x more CO2 than trees do.
