I thought that this thread was about camo but it strayed...........
What did your grandfather wear when he went hunting? His father? The camo fashions appeared in the latter half of the previous century. I do not wear camo but use fabric and leafy-cut ASAT to hide my trail cameras. I do not try to hide. They know what I look like, sound like, smell like so no surprises. I drink a lot of coffee and leave 'Catmandoo Pale Ale' everywhere.
Camo with green is for hiding from humans. The fabric dyes for green can not duplicate a 'biological green' in nature. This flaw is a major problem at sunrise and sunset with the change in the color temperature of light and animal vision changing from rod vision (B&W) to cone vision (color).
Seems like the 1st Axiom of Sasquatch has been forgotten by most: Sasquatch finds you.....you do not find them. I believe personality has a lot to do with 'being found'. There is no camo to hide a bad personality. Even with a 'personality transplant', some people will never 'be found'.
I plod along, normal clothes (501 Jeans) with 'no surprises'.
BTW, your clothing makes a lot of noise in the ultrasonic region when you move. You can't mask it. Synthetic fabrics create the most noise. Wool is the quietest. What did grandpa wear?
