Layers, no matter what, LAYERS. Any and all forms of weather and temperatures can occur in CO during the bow season, sometimes all in one day. Want to go cheap, dying what you have and then layer with another camo pant/ shirt or surplus wool pant and a wool shirt from ARK store or other 2nd store. Got lots o cash to spend, many of the above ideas are spot on. Middle ground budget, look at Day One Camo. Good products, good service. American business. Or, the bigbox outdoor stores too.
Layers, versatile for weather and for matching the surroundings you hunting in. LAYERS.
