Thermos Flasks

[Dan_K]

Anyone use them for bivvying?
We normally tend to carry one when out walking for the day but I hadn't thought much about using one for bivvying.
Bought a new one the other week to replace a battered old one I had. (New one is a Thermos Ultimate 0.8L). Was really impressed that it kept coffee hot for 12 hours and warm enough to drink after 24.

Got me thinking that it could be a real lazy way to avoid carrying a stove and that whole cooking malarkey. I've seen on the Yetirides blog that his mate sometimes uses one.

I've got a .3L one that I sometimes take on day rides, never taken it on an overnight excursion though. I can see that it might be handy on multiday trips if there's not much hope of finding a brew along the way.

After mislaying my usual folding cup and taking a flask in it's place I'm now a convert to taking one along on a cold weather camp out. I filled it with some home made moroccan soup for the journey out and found it kept my tea and hot chocolate warmer for longer as I used it as a mug around the bivi plot. I then filled it with real coffee for the trek back off the moor. Well worth the minor weight penalty and my flask also fits snugly in a bottle cage with it's neoprene cover in place.....

Lightweight titanium thermos? Worth it for the description alone
http://global.rakuten.com/en/store/shug ... /10003905/

It became the new model and came home! Super light weight! Approximately 0.26 kg of titanium bottles!
It is not rusted, and it is kind to skin, and a metal smell does not make it; care simply! I do not do a screw. The glass which it is easy to turn.

Anyone used one of these? http://www.wiggle.co.uk/elite-deboyo-st ... tAodNWoA6A

Gets mixed reviews.

This is the one I've got. Impressive so far

Does anyone use a Thermos for cooking?
I'll be collecting this one tomorrow.
With only being able to boil water with a Jetboil, you're pretty much limited to Ainsley Herriot couscous and Pot Noodles. Being able to "simmer" food in the thermos opens up a whole new range of not quite so instant dried foods, or even the possibility of cooking real food.
At ~380g and 90mm diameter by 167mm, it's not too big to pack on the bike.

Do NOT put a double walled pot on a stove, pressure will build between the walls and the Thermos will explode

Er...yes...it's got a plastic base as well.
That's why I put simmer in inverted commas. What I meant was tip the boiling water and dried food in the Thermos and leave it in there for however long it takes to cook. This should have more or less the same effect as actually simmering over a low flame, with the added bonus that you don't have to keep stirring it to stop it sticking, so it should be good for porridge.

Edit to add;

Haybox cooking has been around for centuries. http://en.wikipedia.org/wiki/Haybox
There are a few modern commercial versions available, but they are all far too big for solo bikepacking.

The only one that looks useful is the Wonderbag.

The big advantage with the commercial ones is that the cooking pot drops straight in to the flask.
Boiling the water in one container, then pouring it in to another, it will inevitably lose a little bit of the heat.

Search on here for 'pot cosy'. There's loads of topics from a while back.

I was going to say pot cosy ... weighs slightly more than bugger all and helps protect your pot too
