Unbleached Cotton

This diaper has raised the standard for One Size diapers since it's creation in 1992. Designed right the first time - our famously durable Cotton Terry is the most popular diaper sold by Mother-ease.

Stay Dry on Cotton

This is the same design as our One Size diaper but has our exclusive 100% polyester stay dry liner sewn to the inside. Great for any time you would like a stay dry barrier between your baby and the diaper.

Organic Cotton

This is the same design as our One Size diaper but made from 100% organic cotton terry.

Organic cotton is becoming increasingly popular as it is grown without the use of harmful chemicals that have an adverse effect on the environment. Ring spun, combed cotton yarn ensures a top quality grade of cotton. Our Organic Cotton Terry fabric is available in its natural unbleached finish.

Bamboo Terry

This is the same design as our One Size diaper but made from our specially knit bamboo terry. This terry fabric is specially knit with 57% Rayon-Viscose Bamboo fibre / 25% Cotton / 18% Polyester. Polyester is knit into the base of the fabric to provide strength, durability and shrinkage control. Our Bamboo Terry is available in its natural unbleached finish.

Bamboo fiber is considered a sustainable textile and grows without the need of herbicides and pesticides. The bamboo used in our yarn is a man made fiber using the viscose process. It is made from organically grown bamboo and the factory producing it follows strict environmental standards (ISO14001:2004) as well as employee health standards (OHSAS18001:1999). This yarn has been tested free of harmful substances according to Oeko Tex Standard 100 for baby articles.
