these were first released in 1993 and they do have sap not tons of it but a little of it . in 1995 procter and gamble made them thicker and more sap and are the ones everyone likes the best ..In 1999 the company was sold to paper pak and they changed them a little bit .the tapes are narrower and the padding was not as far out in the wings but was thicker were a man or a woman pees 'called a dry patch by paper pak. either of the 1995 or 1999 are my favorites .in 2001 paperpack changed the tapes of the ones made in canada to a white tape with blue attends written on the ' the plastic was changed alittle and the tapes held better .in 2003 they were discontinued and any made after 2002 are very inferrior to these.
