The Juban or Hadagi is usually worn under traditional Kimono or sometimes under a Samue to avoid skin contact with materials that are not the most comfortable ones.
It is also often worn by Iaido, Kyudo and Kenjutsu practitioners under their jacket, for the same reasons.
100% cotton is definitely the best material for your skin, making this model extremely comfortable.
This model is designed as a Tshirt, which makes it easy to wear, and stay in place under a Dogi during intense practice. Most recommended for Iaido/Kenjutsu practice.

We especially recommend the Juban with the Tetron Iaido Jacket which is not very comfortable on the skin, because of the tetron fabric.
Also, give it a try if you feel a little cold in your Dojo, no matter what jacket model you wear.

Juban are unisex and can be worn by men and women equally.
Can be machine washed in cold water.
