The coldest so far I've been out in is about 30 degrees F, but this is my first year bowhunting and it only stayed like that for a few hours. I couldn't see myself staying out for very long if it's much colder than that with no wind. If there is a lot of wind to increase the windchill to the point where my feet and hands are REALLY numb, I'm gone. There is a limit as to how big your gloves are and how thick your support arm is before there are sting interference problems.

Today, right now it's in the 70's as I type this here in VA, I didn't go out because of the heat. I'm praying for cold weather, even though I hate it when it's too cold.
