Looking at the Jetboil and Brukit, they come with insulated pots.
The Brupot also comes with a removable neoprene pot cosy, although I can't see anything on Alpkit's site to say whether it needs to be removed when cooking.
Presumably, the integrated stoves and pots have been tested and proved safe so that there's no risk of burning the pot cosy. Mixing and matching other stoves and pots carries the risk of the flames extending beyond the base of the pot and setting fire to the neoprene.

So, assuming I've already got one of these, http://www.gooutdoors.co.uk/hi-gear-bac ... et-p287230, would it be a good idea to buy some of this, http://www.pennineoutdoor.co.uk/wetsuit-neoprene-strip and experiment somewhere safe with a bucket of water to hand?

My pot cosies are made of silver foil bubble-wrap stuff and I just pop the pot in after the water has boiled or when I'm ready to eat. It's simple, easy to customise and cheap.

The BruPot instructions say cook without the neoprene cover.

It is tricky to fit over the handle though so fitting it while full after cooking will be hard.

Neoprene pot cosies burn extremely well with much smoke and swearing.

Ask me how I know.

The Neoprene covers aren't really cosys in the true sense ... they're more insulated covers to stop you burning yourself on the hot pot.

I use my jetboil all the time with the cosy on iv never had a problem as the heat exchanger at the bottom keeps the heat n flames nicely out the way. Like stu says though its only really to stop u burning ya hand oh and a handle which on the to version is crap.

I received an mKettle from someone on here with a few scorch marks to the neoprene bit (ahem, Stu ). TBH when I've used it I leave it on and it's generally fared fine. I also thought the Jetboil ones were fine to use with the cover in place whilst running the stove.

Dunno. Pot cosies are too heavy, I don't carry them
