My dad killed many deer in blue jeans before camo was a big thing.
I kill plenty of deer in jeans these days.
All the camo stuff unless on birds, is a lot overated.
Even on doves and such I may toss on a camo t shirt, but what good is that with white arms.. almost alwasy only wearing blue jeans for them.
As noted, reflections and movement and not being smelled are the biggest things...
Have killed with blue jeans and white tshirt on before too...
