If this is your first Elk hunt I am hoping that you have a guide or an outfitter lined up to help you. They should have a list of gear and clothing that you will need. The biggest thing out west is to make sure you are in shape before you go. I have seen it a million times. Guys book western hunts and go out there out of shape and can't enjoy the hunt because they have cramps all night long. Get in shape now and it will make the trip that much more enjoyable.
