Introduced as a complement to the Bambineo diaper, these doublers are fantastic with any diapering system! Doubled in a Bambineo and you have a perfect overnight diaper - even for heavy wetters! The doubler is made from bamboo terry fabric which is a highly biodegradable product and is grown without the use of pesticides. Even better, it is naturally antibacterial (even after 100 washes) and absorbs 60% more moisture than cotton (it becomes more absorbent with every wash, reaching full absorbency after about 10 washes)! It is beautifully silky soft and remains a soft luxurious texture against baby’s skin even after washing. The bamboo terry is 90% highest quality East Asian bamboo (cultivated) woven with 10% polyester for strength and durability.
