4 Reasons thousands are switching

to Kumori each week


Why Thousands of Men are 

Switching to Kumori Bamboo Underwear

Breathable Bliss with Kumori Bamboo Fabric

Natural Ventilation

Kumori's bamboo fabric allows for natural airflow, keeping you cool and comfortable


Moisture-Wicking Magic

Our bamboo fabric excels at wicking away moisture, ensuring you stay dry and fresh throughout the day.


Odor-Resistant Charm

Most popular brands use cheap fabrics that trap odor, however bamboo possesses natural antibacterial properties, curbing the growth of odor-causing bacteria. 

It's no exaggeration...

Our boxers and briefs fit PERFECTLY!

Stay Put Waistband

When making a waistband it's all about finding the perfect balance. Some waistbands are wayyy to tight!

BUT if they're too loose they fold over. We spent countless hours researching and testing to find the perfect middle ground!


Contoured Pouch

Our contoured pouch gives you the support your junk needs but provides enough room and comfort so you can wear them all day long!


Room for guys with big legs and big butts

Self explanatory. Most products don't give guys enough room!

We gave a little extra room in the thigh and butt area but still enough compression to keep you supported.

Kumori is the eco-conscious choice as bamboo, a renewable resource,  is the foundation of our products.  We prioritize your health and comfort through the purity of natural bamboo.


Many popular underwear brands use synthetic materials because they're cheaper! Here's why you should avoid them:

  • Synthetic material traps odor.
  • Often made from plastic and oil byproducts. 
  • Holds on to bacteria and toxins.
  • Not Bio-degradable.
  • Linked to many health risks.

No subscription traps – you decide when and what to buy. The more you buy the more you save! So you are able to get premium underwear at an affordable cost per pair!


What's even better? Always have a clean pair with Kumori's large packs. No more last-minute laundry stress or wearing the same pair repeatedly. Our packs offer a variety of colors so you can mix it up! 

Not to mention...


New customers get an additional 20% off their first purchase when they sign up using their email.
