The Montana hunting seasons can be warm and enjoyable or they can be extremely cold and wet. You should have enough clothing to stay warm in zero degree weather. I prefer layers to a one piece suit. The guides and I use wool pants and shirt and some type of quiet coat, usually wool, snow packs and gloves. Here's a partial list of things you might need.
Necessary Items: Hunting license Fluorescent orange hunting vest, the quiet cloth type Rifle and bullets Knife Flashlight Binoculars Extra gloves Personal medications Canteen Hiking boots and wet weather boots Cold weather gloves and coat Hat Day pack: large enough to pack a lunch, water, knife, flashlight and some other gear.
Extra but Not Necessary Items: Sun glasses and suntan lotion Hand warmers Range finders and other hunting devices Book to read Spotting scope Leatherman or other multi-tool
Items Not Needed: Sleeping bag and pillows Extra rifles
