Favorite water bottle to prevent frozen water?

Trying to keep my water liquid! Weight is definitely a concern and I can easily start with boiling water as i am just doing things car to car. Any hydration mixes that noticeably lower the freezing temperature of water?

I’ve used one of these for a long time. Seems to have doubled in price!

yeah those do seem pretty expensive and bulky compared to metal ones.

There is no way I would spend $92 on a water bottle parka. Maybe $15.

I'd wrap my water bottle in aluminized bubble wrap and duct tape

dunno what temps you're out in, but my standard 1 L nalgene does fine inside in one of these on car to car winter missions. overnight is a different story...

I also have the OR water bottle parka, but i don't recall paying that much for it. maybe $40...

Hmm that does look pretty nice. The mission I have in mind is about 20 hours of temps between 5-20F. 

Ive used a hydroflask thermos, and also a hydraflask stow 500 ml in a chest pocket.

there's also the classic water bottle cover from 40 below, but i personally think these are overkill for day trips...

I have had pretty good luck on cold PNW ski tours using a combination of simple methods to keep my water liquid.  I use un-insulated smartwater bottles or the like.  

• when possible I fill the bottles with hot/warm water, keep them in a warm spot on the drive to the TH.
• store the second half of the day's water deep inside my touring pack, ideally near the center of the back panel and near the extra layers stuff sack where it's well insulated by things I'm already carrying.
• on especially cold missions I use re-usable hand warmers which are like magic. Each one weighs almost exactly what one of those parkas weighs and will warm the bottle back up to 100F or so over the course of 2 hours. I take one per liter and activate them midway through the day. Usually just have a rubber band holding the warmer to the bottle. Can be re-activated in the field if you have a stove, like on overnight missions.

The smartwater bottle and warmer come in at 225g per liter while the Nalgene and my old OR parka are around 325g. For a not-nothing ~1/2lb savings if you're taking 2 of each.

A sewing machine and some old jackets would make for some quick bottle-cozies. I have some OR cozies from the 90s that are basically a tube of synthetic poof like a retro vest. 

Not that you prolly wanna spend $70, but Hyperlite makes a water bottle parka now, called The Insulator.

Hyperlight has gone off the fucking deep end

$0.10 plastic water bottle from Walmart etc. upside down inside a spare mitten.

I use a 2L platypus bag stuffed between my emergency down mittens in a Hyperlite stuff sack.  Zero extra weight since I'm carrying the mitts anyway.  Keeps water warm all day when backcountry skiing.  Doesn't slosh, shrinks as you drink.

absolutely would not work, have tried before and got very dehydrated

As we speak I’m comparing the classic 40 below vs. a $15 Liberty Mountain parka in my freezer. So far two hours in they perform the exact same. Go with the $15 liberty mountain parka, found on Amazon. Having said that if you like supporting small business get the 40 Below. OR and HMG are off their rocker for charging the prices they do for their products.

Take two half a liter bottles and put them into a pair of spare mittens.
In winter you do not lose that much water and one liter should be enough for a typical day (unless you spend the whole day at the top of your Zone 2).

I really don't see the problem?

What? I thought the lower relative humidity and breathing at altitude caused you to use more water, or I guess loose more water through breathing.

I find that taking less than 1 1/2-2 liters for 20-26 hours at moderate altitude slows me down from dehydration more than the weight of an extra liter. But I do hear you though, I agree a lot of people bring too much water winter climbing 

I don’t have spare mittens and would inevitably end up wearing my thickest pair of gloves during the coldest part of the day when the water is most likely to freeze. 

Thread drift. I know OP is concerned about weight. If not, use a thermos! For day trips or hub and spoke multi days I use a thermos and always have near boiling liquid. I wouldn't take it on up and overs or where space and weight are a concern, but for days where the approach isn't the crux I actually want to drink and it revives me and my partners from the worst parts of the day.

Otherwise I was using 40below bottle booties and wrapping this with jacket\gloves etc. but I always had pretty frosty or just frozen water by the end of the day. The chemical warmers seem like a good addition to try.
