Hellas I am looking for advise on a what sleeping bag I will need to backpack in 2-3 miles from base camp ( where the rest of our party is ) during the second rifle season . This past season it was in the low twenties and I would get a little cool at night while in my browning zero degree bag . I was camped at about 9500' and the area I am looking to hunt is 10-11k. I was sleeping on a cot with a 2" foam cushion on it . In addition I sleep in poly thermal long underwear , socks and a sock hat . I am 6' 2 " 250 lbs so I am partial to the bag I have but freezing is not an option (I froze in 96' when it fell to 3 degrees and I was in a 30degree bag) . I will be only making 1 trip in and out so it is not a deal breaker to pack a 8 lb. bag if necessary. Also those of you that that doe this type of camping / hunting what combos are you using ? and any secrets to keeping warm at night (diet, ect.). Also I will be sleeeping in my 2 man tent .
