Hi all,
I have lived & worked in the Arizona high desert which doesn't get as hot as the low valley deserts like Phoenix. Our soldiers can bee expecting 145 degrees.
Any place cloth rubbs can cause a chapped place or a rash even with 100% cotton. Powder helps but disappears quickly.
Polyester is really like plastic. It's hot in summer, cold in winter.
Test an old garment with a match & see how it melts. Perform the test wisely, polyester burns quickly.
Have you ever let your iron get too hot for pressing a synthetic garment & have it stick or melt to your iron?
I'm going to put a some Zinc Oxide in a few boxes. See how that goes over. It was used to protect against sun burn before sun screen was developed.
Yes it is also ointment for diaper rash. Sweaty waste bands are irritationg to the skin. The only thing I'm worried about is how sand could stick to it. If they can't shower that would be like wearing sandpaper.
