Frequently Asked Questions
What makes Kumorio bamboo underwear different from regular cotton underwear?
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.
Is bamboo underwear good for sensitive skin?
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.
How should I wash and care for my bamboo underwear?
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.
Will bamboo underwear shrink after washing?
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.
Are your bamboo briefs and boxers eco-friendly?
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.
Do the briefs and boxer briefs have a tag-free design?
Yes, all Kumori underwear is tag-free for maximum comfort. You’ll never have to deal with itchy or irritating tags.
What sizes do you offer?
We currently offer sizes from Small to XXL. You can view detailed measurements on our Size Guide page to ensure the perfect fit.
How does bamboo fabric perform during workouts or hot weather?
Bamboo viscose is naturally breathable and moisture-wicking, making it perfect for active lifestyles or warm climates. It keeps you dry, cool, and odor-free even during intense activities.
Where is Kumori bamboo underwear made?
Our products are ethically made in certified facilities that follow sustainable manufacturing practices, ensuring both quality craftsmanship and fair working conditions.
What is your return or exchange policy?
We want you to love your Kumori underwear. If you’re not satisfied with your first pair, contact us within 30 days for a hassle-free return or exchange. (Hygiene rules apply; see our full Return Policy for details.)
