Sure wearing pants that completely deviate from the norm is silly but can we avoid ridicule of those who go for the hpi pants or any other equivalent? If "shiny polyester" is what Spirit designate us from the supplier, then 'shiny polyester' is the uniform!
Training pay is a struggle enough for a lot of us as it is. If you buy from the vendor, then you're in compliance. Ill shine my polyester right into your non training pay eyes any day of the week.
