I don't mean comfort tests - I've already done that! I mean that I want to know more about the material - white nylon - which is not rated positively as "food safe" and in theory may be porous.
I did two tests - and I should state now that I'm not any kind of scientist.
First, I weighed the device, soaked it overnight, shook off the loose water and weighed it again. End result, same weight before and after. I conclude that the nylon material did not soak up any water. It follows that it's actually solid behind the eggshell-like surface. No wicking takes place.
Next, I wanted to check the surface. The texture is great for comfort, but is it a bacteria trap?
I figured the real question is; Can I get it clean?
