I can tell you that my Grandfather never owned anything camo, used regular soap, shampoo and deodorant. If the truck needed fuel he stopped and put it in, never hunted off the ground. Never owned a gps or a range finder or even a scope come to think of it. He was still one of the best hunters I have ever known in his kacky Dickey’s work pants and shirt and Resist all 4 x rancher.
A lot of things can help you to be successful but none more than skill.
