There has been a lot of talk about this on other forums that I have been on. Plastic pants over disposable diapers offer very little additional protection. They are good for preventing spotting if you have a small leak, however if you have a major leak the urine will just travel between the two non-absorbent layers and find its way out (usually through the leg openings). The best way to prevent this is to wear cotton briefs over the disposable, under the plastic pants. That way if a leak does occur the cotton briefs will absorb the urine and the plastic pants will keep it from getting to your outer pants.

I performed a "dry" run so to speak on my kins plastic pants. I leaked in a seated position a couple tiems in a row. The urine pooled in the bottom of the diaper and leaked out the leg opening. It got into my plastic pants from kins and leaked out that leg hole as well right onto my shorts. So I'm at a loss. I don't know what to do. People say the plastic pants contain the urine. I don't see how. These are good pants. And they leaked. I'm still going to wear them. In case I leak stool. I'm hoping they will contain that being they don't contain urine. Maybe if I was to leak in a standing position that would be different. I'm thinking the urine would pool in the bottom of the plastic pants, like right in the crotch. But I don't have a lot of experience in this matter. Hopefully, some of you who regularly wear plastic pants can enlighten me on this matter.
