New Balance jersey pants, 100% polyester, with an elastic waistband for a comfortable fit. I have worn these for about 3 months in a childcare setting. There is some wear on the knees and wrinkles behind the knees. The size is also large, so they fit loosely and are easy to move in. The original purchase price was about 7500 yen. - Brand: new balance - Color: Black - Material: 100% Polyester - Style: Jersey pants - Features: Elastic waistband Thank you for looking.
