Question on self-wicking polypropylene fabric

I will be sewing self-wicking polypropylene fabric for sports underwear. The fabric has a very smooth side and a somewhat meshy side. I want to know which side to use next to the body. It is critical that any sweating has to wick AWAY from the body.
I have tested (with sprinkles of water) on both sides to see which wicks away the moisture fastest but there wasn’t a lot of difference. I suspect the meshy side should be next to the body but want to be absolutely sure.

self wicking polypropylene
Just to let anyone who might be interested in this post, I have found the answer. It took ages and ages on the internet and I needed to be sure which side went next to the body as this is self-wicking fabric used for warmth. I found a manufacturer in Australia that makes extreme sports and military wear and they were extremely helpful even though I explained that I was sewing this for myself, I got several email replies with a good explanation of the fabric's attributes and even a photo of their crew onboard the company's racing yacht!
So, for anyone sewing self-wicking fabric the meshy side goes next to the body although the difference of the two sides is hardly discernible under a good light.. It took no time at all to sew stretch leggings and t-top from a pattern that has been in my collection for decades. So thank you Phil Endersbee of Wildernesswear.com in Australia.
look at a manufactured sample
you can also check into an aerobics store and see how their's is made.

Yes, I did that but the fabrics they used were heavier; mine is feather light and specifically made for long underwear for cold weather.
