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.Feb 21, 2011 at 2:38 am #1699434

Have used reflectix in past. Also could use foam tape or closed cell foam.Feb 21, 2011 at 4:30 am #1699440

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)Feb 21, 2011 at 8:54 am #1699502

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.Feb 22, 2011 at 5:43 am #1699882

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.Feb 22, 2011 at 6:32 am #1699895
^ that's a good idea :)Feb 22, 2011 at 9:50 am #1699975

I have an insulated sleeve, with toggle cord for Nalgene bottles. Works good also with other Ziplock or type container.Feb 22, 2011 at 3:33 pm #1700143
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 thoughFeb 23, 2011 at 2:49 pm #1700657
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.
