If you're going to be hunting with rifles I'd suggest buying a blaze orange hunting vest that has some sort of camo pattern, like Seclusion 3D Blaze. It will do a lot better job of breaking up your outline than plain blaze orange. For the rest of your clothing, follow the advice of wearing moisture-wicking long underwear, and be sure to layer instead of wearing one big parka. Don't worry too much about buying the latest and greatest camo if you're rifle hunting either, because you should be staying out of the elks' vision as much as possible anyways. Good luck!
