About Bamboo Charcoal Fiber

Bamboo charcoal, also known as 'Black Diamond,' in Japan is one of the most multi-purpose substances that can be found in household products, beauty products, textile bedding, and even food.


The secret to bamboo charcoal’s antibacterial function falls behind an antimicrobial bio-agent found in bamboo called 'Bamboo Kun'. Our bamboo charcoal fiber is certified by SGS, that the fiber is able to prevent the growth of common bacteria such as E. Coli and Staphylococcus Aureus.

SGS is an international inspection agency based in Switzerland which provides inspection, verification, testing, and certification service.


Bamboo charcoal contains millions of pores, allowing it to absorb and degrade certain toxins, odors, and allergens.   

Bamboo Charcoal Fiber as Duvet Insert  

After absorbing body temperature, bamboo charcoal will emit far infrared rays which help to improve micro-circulation and provides great insulation.

Extended sides: Allow fillings to breathe in the fresh air every time you make your bed.

Security Loops: Can be tied up with a duvet cover to make sure the duvet stays in place.

Construction: Duvet can provide consistent warmth even after washing.
