Cotton’s intrinsic moisture absorption and heat generation
Cotton is a natural material that has the function of absorbing moisture and generating heat. Through a special process that enhances these abilities, we have created warm innerwear.

Prevent static electricity
Because cotton is a material that does not easily pick up an electric charge, static electricity is not produced easily, even if you wear knitted wool fabric on top of it.

Prevent your skin from drying
Cotton, which does not absorb your skins oils as much as materials made of chemical fiber, is a gentle fabric for the skin during winter when it tends to get dry.

Gentle touch to the skin
In search of a gentle and comfortable fit, we removed the seams along the side to reduce discomfort. To prevent irritation caused by fabric care tags, we put the tags on the outside for children and implemented a tag-less design for adults by printing the instructions onto the fabric.

Gentle to Both Human and Nature100% Organic Cotton
Cotton is one of the most precious
natural resources to MUJI.
For more than 20 years, MUJI has been continuously working to increase the percentage of organic cotton used as cotton material in apparel and all cotton used in our apparel has become organic cotton since 2018.
