Fit is quite a big point . 1st you need waist size, 2nd you need width around thigh, 3rd you need waist to back measurement through legs. 4th look for pants with forwards facing leg holes. important if sitting as it gives a much better fit,( i use a wheelchair so this is important for me).makers will give a size range ie waist from 28'' to 36 ''' look at your waist size and remember the pants have to open enough to go over the diaper. crutch width go large as this will allow thicker padding, plus allow you to spread legs wider for going up a stair .thigh diameter is very important too loose you leak too tight you can burst leg band and end up with sore red rings around legs,( it hurts). this is really a question that could take for ever to answer so many variables. Go for the best quality pants you can afford. keep all oils and creams away as most tend to make the plastic and rubber deteriorate fast. bye all means drop me a message if you need any help in this area.
