QUESTIONS? WE HAVE ANSWERS.
Our bamboo briefs and boxer briefs are made from ultra-soft, breathable bamboo viscose. They're naturally moisture-wicking, antibacterial, and temperature-regulating — keeping you cool, dry, and fresh all day long.
Yes! Bamboo fabric is hypoallergenic and naturally smooth, making it ideal for people with sensitive skin or allergies. It's free from harsh chemicals and dyes that often irritate the skin.
We recommend machine washing in cold water with mild detergent and tumble drying on low or air-drying. Avoid bleach or fabric softeners — they can damage the bamboo fibers and reduce softness.
Minimal shrinkage may occur (around 3-5%) if dried on high heat. To maintain the original fit and softness, it's best to air dry or tumble dry on low.
Absolutely. Bamboo is a sustainable resource that grows quickly without pesticides or excessive water. Our bamboo fabric is OEKO-TEX® certified, ensuring it's safe for you and the planet.
