Seat Padding built right in. Like New with minor exception. 2" of stitching where the padding is attached to the shorts has come undone. You can see from the cover photo on the left side outline of the padding. Simple stitch on a sewing machine would render these 'like new'. REI, bLACL Size Large. Co-Op, either gender. Thanks for checking these out , have any questions just ask in the comments below.
