New pvc waders and sauna top

[Nylon macs]

I recently bought a sauna suit top silver one .and a pair of lovely pvc waders with attached feet .
It was secondhand on ebayuk.
On washing it and now eager to try it on .
I washed it in the bath and popped it on a hanger to drip dry.
On closer inspection I noticed it's got teeth marks on the crutch and rear aria. And now very intrigued to know if they used it for the same things I get up to in all my pvc gear. The same with the suana top its also got teeth marks on it . And it all needed a good wash before I can use it.
Mmmm
