I believe camo pattern is for humans, most animal we hunt doesn't have good eyesight. Depends on your method of hunting, if you hunt from tree stands, you need cloth that keeps you warm and dry. The cheap route is to buy military surplus cloth, considering our military use G wagon, the mil surplus clothes should be quite decent, there is a good mil surplus store near Port Credit. if you have a big budget, you can go to Cables or Basspro get the Gore Tex camo. The big thing to lookout is not to wear cotton, cotton tends to hold sweat and rain. wool and polyester are better. Sometimes Costco has affordable merino wool and polyester blend base layer. Shoes are important, but
heavy insulated ones aren't cheap, I normally wear thick wool socks, use chemical toe warmer.
A lot of times I just use my winter clothes for short weekend hunts. Now, when I shop for winter clothes, I pick green or black with little noise.
If you want to get close to the animals, you need to control the odours. Use no scent soap before hunt, and put your hunting clothes in a dry bag.
