Granite Gear on 02/20/2011 21:31:12 MST Print View

Granite Gear makes (or at least used to make) two nice models: Aquatherm and Aquasack. The therm is foam insulated, the sack uses reflective bubble insulation. I bought the therm for a friend and made a homespun version of the sack (same process as a pot cozy). Both worked well; mine wasn't as warm.

I personally prefer to avoid zippers, finding GG's drawcord and insulated flap system to be much easier.

Have used reflectix in past. Also could use foam tape or closed cell foam.

looks good on 02/21/2011 07:43:32 MST Print View

like the design of the previous Granite Gear one, looks like they've change the design to a zipped one now- dubbed the Air Cooler

the OR and 40 below both look well insulated, is having the top covered/insulated a must have if the bottle is stored upside down?

I might have to try a diy w/ some 3/16" ccf (and some gorilla tape)

EMS H2O cooler. on 02/21/2011 09:54:56 MST Print View

OR also makes something almost identical to EMS's H2O cooler; these are standard for keeping water liquid here in winter hiking.
MYOG version is made with foam and duct tape.

Old wool sock. I took a sock that I retired from normal wear and repurposed it as a bottle cozy. Store bottle upside-down in pocket. Old sock is multi-use (cozy, emergency extra sock, mitten, pot grabber, etc.), as long as they're dry. Worked great into the teens on many trips. Have yet to test insulating abilities in the summer.

Nalgene Sleeve on 02/22/2011 12:26:00 MST Print View

I have an insulated sleeve, with toggle cord for Nalgene bottles. Works good also with other Ziplock or type container.

eric - that's where i have been keeping them, but would like to move them out to free up some room

a simple neoprene sleeve would probably be the lightest option, not sure if it would do the trick in really cold weather though

Second using wool sock on 02/23/2011 15:49:55 MST Print View

I just use one of my backup pairs of wool socks... keep the bottle upside down and in pack/sleeping bag or in pocket next to body and it works pretty good in my limited experience.
