Yoga mat. Convenient to carry with a strap. The one in the photo is a yoga mat, 6mm thick. It fits a 61 x 173 size. Please note (case only for sale). As this is handmade, please understand that there may be some slight variations or misalignments. The stretchy fabric makes it easy to put the mat in and take it out. It won't be a problem when carrying the mat over your shoulder. This type is the last one. Thank you for viewing.
