I don't know if this interest you or not but a couple tips I use!
but all my pop up blinds I have used, all had a SHINE to them I didn';t care for
I found a way to get rid of it by, I got muddy water and dumped it all over them
I figured when it dried it would leave a duller finish, add maybe some more natural scent to things as well
I also never open ALL the windows, as doing so you stick out in it, having a window open behind you
I only open as small as possible too
