I just thought I'd bring up a subject I wrote about awhile back.How to keep liquids in canteens from freezing in very cold weather.I stumbled onto US surplus Artic canteens on ebay,sometimes they even put up several new in box artic canteens.I bought one for for under 10.00.These are double walled insulated aluminum canteens that keep the liquid from freezing.They do not have thread screw caps so the cap can't freeze shut.Just thought I give you guy's some info I had in case ya was interested..
 
When winter camping, I always boil water at night and put the water in closed nalgene bottles in my sleeping bag. The water keeps you warm part of the night and your body keeps it from freezing the rest of the night.

During the day, put your canteens/bottles upside down inside foam (you can make your own pouches out of an old foam pad) pouches to keep the threads around the lid from freezing. If you carry widemouth bottles, you could always poke through the ice with a knuckle if needed. It isn't so easy to do with narrow bottlenecks.

By the way, stay away from Camelbacks in the winter. If you do insist on one, wear it inside your jacket between your body and your pack. Thread the tube under your arm and keep it near your body at all times. Don't blow the ice back into the resevoir as it will cool it down and increase the likelihood of having the whole unit freeze on you.

Hope this helps.
 
Okay,I filled the canteen up half way with tap water and froze it in my freezer after the above formites suggestion as a test.It wa in freezer for over 12 hours.It did freeze some,but water started coming out in smaller quantities right away.I would suggest keeping canteens as full as possible to avoid any icing.It also suggests that the inslulated Artic canteens do significantly increase the likelyhood of your water remaining unfrozen in severe cold weather.Hope you all injoyed my scientific testing ;)
