Pee Bottles
This gives you a few meters of gaffa tape for running kit repairs, its also a lot easier to identify which is your pee bottle and which is your water bottle in the dark!
Steri Pens in the Cold
I suggest placing the whole pen in your sleeping bag with you that way you are ready roll first thing. I found that in the himalayas keeping the batteries alone in your sleeping bag was not enough. Also its a lot less hasle by not having to remove the batteries.
