Dark gray yoga pants with an elastic waistband. - Color: Dark gray - Size: Approximately 90cm (total length) - Waist design: Elastic waistband Thank you for viewing. I purchased these on Rakuten and tried them on twice. They are made of smooth, thin, soft fabric and are comfortable with an elastic waistband, but they didn't suit me. They are not the rubbery, shiny type, but rather supple. They could also be used as pajamas or loungewear. The waistband is elastic, and there is a 2cm wide band inside that moves. There is no size indication, so it's free size. These were top-rated yoga pants, but they are not originally from an expensive yoga specialty store, so please be aware of this.
