Boots for sure. I hunt steep and deep in Colorado mountains. Terrain is brutal on the boots so pick good ones. Sore beat up feet will end your hunting in a hurry. If you are rifle hunting, assume the weather will change a lot during the day and day to day. Base layers are a must but an overall layering system is key. The more flexibility you have to regulate body temps the better. I always wear gaiters. Between dewey mornings and snow/rain showers, there is usually a high probability of getting your boots wet without them. Finally a good water purification stem is a must. You will find you drink 4-5 times amount of water you normally would which is probably half of what you really need to drink. No way to carry all of that with you when you can refill along the way.I plan on going back, but I’ve never been out west hunting before so it’ll be a new experience but I do have the feeling that once I take my girl out there it’ll be a yearly thing for sure. Sounds like boots, base layers and binoculars need updating for sure. Bass Pro trip for Mother’s Day!
