A washably reusable diaper having water wicking inner layer, a water impervious outer layer, a space in between for insertion and removal of water absorbing pad and having an elongated pocket adjacent to the waist line of the diaper a nd an elongated pocket adjacent each leg line of the diaper. Disposed proximate each end of each elongated pocket is a means for releaseably attaching an elastic strip. In each of said pockets is an elastic strip having a number of mating means disposed along the length of the strip. Accordingly the length of elastic strip in each pocket may be selectively varied as the wearer of the diaper grows, for use on different wearers and the elastic strip may be easily removed and renewed when necessary, extending useful service life of the diaper.
