Good advice from all. I hunt 2nd rifle for Mule Deer up around Kremmling/Steamboat. Most of the time I'm freezing my butt off in the AM and by noon I'm trying hard not to sweat. Occasionally we get a storm in. I do wear a light to mid weight long john. It offers some insulation and wicks moisture. I've worn everything from jeans (not blue) & cargos to carhartt overalls (uninsulated) and have been fine. I have a pair of heavy wool bibs and a pair of gortex bibs that I always take just in case the weather gets real nasty. I haven't used them yet.

Couple things I have noticed: 1) I hunt around 8 - 9K ft. It seems that the higher up you go the more extream the weather can be and expecially above 9K ft. 2) It seems that the hardest thing is balancing how to keep from sweating when you are moving, especially up hill(whichthere is a lot of)vs. how to stay warm when you stop and spot/glass.

I find that I usually end up with the light long johns, pants, a heavy shirt and a layer of fleece or just two layers of fleace. Good boots (I prefer 200 grams), wool sox, Liners, hat, gloves are a given. I take a heavier hat, gloves and coat and can pack them with me if the weather looks bad.

Take a good variety (summer to artic)with you and pack what you need for the day's weather.
