HumanFly, you just lucked out as I can answer your question.
I wear rubber pants and rubber bloomers. After some mislabelling of sizes by Kins, I found that Kins obtained their rubber pants etc. from Protex.
I now buy directly from Protex and am very satisfied with their customer support. Their link is:
https://www.myprotex.com/collections/rubber-pantsYou will find that Protex offers a greater variety of rubber pants/bloomers than what was available on Kins.
Even better, if you register on the site, Protex emails will notify you of frequent sales. These will result in a substantial savings compared to Kins.
