Softwear Regular Height Adult Plastic Pants
As the name infers, the Softwear PVC pants are warm and soft to touch. It is an opaque material, so you will be able to see the nappy / pad beneath.
The pants are manufactured by Gary Manufacturing and are from the USA.
They have front-facing legs and a wide crotch area to allow the nappy/pad behind to be fully protected.
As always for sizing, take the measurement around the top of the leg/thigh and then look at the waist size.
