Thank you for viewing. This is Entwa's "Hizakko Pants." I purchased them when the brand was still called Kazenosumika (Wind's Abode), before its renewal. When my child was small, they were convenient because they allowed him to run and squat without any stress, and they could be washed thoroughly in the washing machine. The elastic waistband is also comfortable. The fabric is suitable for wear in all seasons except for the peak of summer, and I'm selling them now because I haven't had a chance to wear them recently.
