Where I work I'm outside for 5-7 hours a day and with it getting colder out a lot of my time has been being put into research on keeping warm. With the weather peaking at 34°F and a windchill in the high teens having access to a warm bottle of water, tea or soup would be on of the biggest moral boosters. I was think about one of the Stanley vacuum bottles because I could just run up to wal-mart and grab one before work but but I'm hesitant because I don't know how they'll fair out in the cold air being blasted by freezing wind.

So what do you guys think? Is there anything i can do it help keep it warm?
 
A larger thermos is better than small .You could always put the thermos inside a small but efficient cooler like Yeti.
 
Contigo and Hydro Flask both make a fantastic double-walled vacuum insulated thermos. I have a 64oz Hydro Flask that I filled with boiling water and tossed in the freezer. Several hours later it was still hot enough to brew tea. I carry a 20oz Contigo around at work and it kept some hot cider hot for over 5 hours yesterday.

One trick to aid a stainless thermos is to rinse the inside with boiling water to heat it up before pouring a drink into it, so that the cold steel walls can't cool it off at all.
 
Pre-heating the bottle is one of the simplest and most effective things you can do to improve the efficiency of any vacuum bottle. Simply fill the bottle with boiling water and lets it sit for 5-10 min. Then pour the water out and fill the bottle with your warm drink.
 
Most of the heat loss is through the stopper, so choose a narrow-mouth thermos with a solid well-insulated stopper. Some have a hollow stopper with a button you can push to pour -- that might be convenient, but it doesn't insulate. The cup provides additional insulation, so pick one with an insulated cup and keep it on as much as possible.
 
Thinksport makes a dandy double walled thermos. The lid is not insulated, but it is made to sip off of regularly. I find it a lot handier than a traditional thermos.
 
It was 19 when I headed out hunting yesterday morning. I had my Stanley thermos full of coffee. The last cup was still very warm six hours later, the temperature was in the mid 30s then. I did warm the thermos with hot water before adding the coffee and the thermos was in and out of my pack during the day.
 
My best advice would be to find a vintage American made Stanley thermos on that auction site and avoid the el cheapo Chinese made Stanley products. Preheat it with boiling water and you'll be good to go.
 
I have used a Stanley thermos for years. I agree that preheating it works best. I use it at home to keep left over coffee from the morning, it is still warm 12 hours later when I get home from work.
 
All I have to show you is this... Read the reviews, they're accurate. I have one, bought one on a whim (when I couldn't find anything good at Starbucks) and I'm very glad I did. I can only imagine that similar products from REI fitting your capacity needs will work just as well - they seem to have a whole line of insulated mugs and thermos. I took the infuser out as I don't need it. Don't fill above the top-line and align the threads correctly and this thing is solid sealed.

This. The old vintage bottles are also American made and make the new ones feel like garbage. I've been using mine for a few months now to save money on coffee and it keeps it hot till the days end. I don't work in the cold but I feel these are the best you can buy in terms of quality. My particular bottle is 30 years old and works fantastic.
 
Dad had a Stanley thermos when I was growing up, beat to heck and still worked like a charm.

One of my graduation presents was a Stanley thermos, same green plastic, same steel construction, it's been through at least a dozen backpacks since then, out in the fields, tossed in the back of trucks... Solid equipment.
 
I used one of these for several years. Highly recommended.

Mine is not the same brand, but the principle is the same; an insulated mug with a heavy duty seal.
When closed there is nothing to let the heat out and the mug holds liquid hot/warm for hours.
With lied screwed on properly, it wont leak either.
As mentioned above, do pour boiling water into the mug prior to filling it with your beverage of choice.

My old mug has been with me on several tours, kayaking and camping trips. It is now ugly, dinged, dented and scratched beyond belief, but still holds liquids as hot/warm as on the day I bought it in Camp Bastion years ago.
