I routinely hunt whitetail when it is below 20 and I've hunted below 0 a few times when I was growing up in MN. Dress real light whenever you are walking. I've often been seen in my base layers and a pair of pants for a walk with the rest of my clothes in my backpack. I'll change socks when I am stopping and put the rest of my layers on. For water I've often switched to one of the camelback packs that holds 3l of water and only water and I'll wear it inside my jacket and tuck the hose in under my jacket. My body heat keeps the hose from freezing.
Absolutely right on not sweating. I've found a few tricks to keep sweating to a minimum - 1. Leave early – walk slowly. Maybe stop every 50 paces or so 2. Avoid caffeine and spicy foods 3. Apply antiperspirant the night before you hunt. It takes a long time for antiperspirant to clog your pores. You can also try spraying other areas of your body. (make sure it's unscented)Good advice on not wearing a lot of clothes while walking. The last thing you want is to sweat. I've had to completely strip down and remove my soaking wet base layer before and it was not a good experience.
When winter camping, you dont have to get up to pee; it lets all that accumulated heat out of the loft of the bag..... Just hope that you don't have to get up to pee...
You pack in that heavy duty plastic jug for the sole purpose of being able to pee in your sleeping bag?When winter camping, you dont have to get up to pee; it lets all that accumulated heat out of the loft of the bag.
I keep a 32 oz square nalgene bottle in the foot of my bag for nature's call. Its square so that it doesn't ever get confused with my water bottle. Even in a mummy bag, you can roll over to a semi-knee'd crouch to take care of business. That plastic bottle can offer some heat for a little while afterwards as an added bonus
