I've only hunted in first season rifle in Colorado but have experienced temps in the low teens but nothing below 10 so far. Saying that, I use a 32 oz. Nalgene hardsided bottle in a Stone Glacier water bottle holder on my pack belt so I can easily access it while walking or stopped. I quit carrying my water bladder this year because I thought it took up too much space in my pack. For a water filter I chose the Platypus Quickdraw system that you fill a dirty bag in a stream then screw the filter element onto it then you can squeeze it to quickly fill a 2 L Platypus water bag or directly into your Nalgene bottle. the filter element can be easily flushed out at home by flushing from the clean filter side through and out the dirty side and it's supposed to last a long time (relevant to how dirty your water source is I guess). I have two Platypus 2L bottles which I fill up near camp and leave there for meal prep and coffee. I carry the filter and the 2 L dirty bag with me two fill up as needed. There's plenty of water in my elk hunting area but not my mule deer area so I've carried everything in full which is about 13 pounds but I have no choice.
One advantage I like with the Platypus 2 L bottles is I can roll them up when they are empty and they weight almost nothing. They have frozen over night but thaw out with no harm done to them.
