the Thermos Nissan line. They are possibly higher quality than the REI thermos, a little pricier, but well worth the cost. They keep heated contents very warm, or cold contents cold for extended periods of time using double wall vacuum insulation technology.
I Wonder How These Would Hold Up to the Freezer Test?
i know these probably shouldn't be put into the freezer but, i was wondering how both of these popular water bottles (*both available at rei) would hold up in freezing temps and what would happen to the contents inside? here's a link to both the klean kanteen water bottles and sigg brand water bottles:
I agree with others' comments that agitating the bottles would bring a different result.
Personally, I have been carrying three Nalgene bottles with insulating jackets (Granite Gear brand). I just bought an EMS brand jacket that seems nicer (similar to the OR but cheaper). I like to hang one of the bottles on my hip belt (for easy access) and keep two in my pack.
I think that I will try a new strategy: Still use a Nalgene on the belt, but keep one or two Thermoses in the pack (instead of the other Nalgenes). I am going to look into the REI and SIGG models.
Scott, on a related note, I wonder if it would make any difference with #2 plastic Nalgenes instead of #7 plastic. Word on the street is that the "classic" Nalgene (#7 plastic) are not good for you (leaching of chemicals into your drink, etc).
i used a pair of thermo bottles very similar than the REI (but from a European brand... maybe made by the same manufacturer) in an extreme race in northern Minnesota in February.
After 12 hours at -30 F average, my water didn't freeze
Hey! Thanks for posting this! I've done some controlled experiments along these lines as well. My objective has generally been to compare the performance of different types of foam insulators. I have found the Granite Gear Aquatherms to perform consistently better than the OR water bottle parkas. A thermos, of course, is far more efficient, but also a lot heavier. (The thermos in my experiments was also an REI 1-Liter.) See below for links.

In really cold weather I have started with hot water and have also used duct tape to hold a heat wrap around my Nalgene. This also provides a nice way to warm your sleeping bag if you are camping out.
Thanks Scott. You influenced me to buy a thermos. I picked up a Mountain Gear branded model that looks very similar in construction to the REI model except with a black powder coat. I love it.
Filled with near boiling water after over 8 hours in the freezer it was still hot to drink. After 22+ hours it was room temp. So happy with it I decided to keep the 2nd one that I accidentally ordered at the same time.

Thanksgiving test
I will be doing some real world testing this Thanksgiving on Mt Whitney. Last year I had some frozen bottles this year I hope to keep them flowing. I will post results when we get back.
At the beggining of this winter, i began carrying thermos on every trip. I love it!
I make a hot tea with lots of sugar and use it for a warm-me up/pick me up. i got a lightweight floating (mostly plastic) 1 quart thermos from Walmart $18. I works great, even in 20 below weather.

Weights?I'd be interested in the comparative weights of the Nalgene/jacket and two thermoses, if you have them. Thanks. Great test and report!

Can you tell us what thermometer you used?

Great PostGreat post! I'm headed up to Canada for a little "fun" in December/January. I've got a 0.5 L thermos, but may need to pick up a bigger 1.0L one.
