Logic Check: Pot Insulater

A Jetboil, with the heat exchanger on the bottom of the pot, extracts more of the heat from the flame. That uses less fuel (duh!), but it also means the gases coming up the side of the pot are cooler and the neoprene can handle those temps.

Wood stoves, with their variable flame heights, would be much harder to adapt to a neoprene cozy, except a cozy used AFTER removing the pot from the flame. You could potentially put enough heat-exchange function on the bottom of a pot to use a cozy up higher, but it would be a custom effort.

I really like heat exchangers on pots. The weight pay-back is so quick if you use fuel and, of course, dinner is ready that much sooner. If you do any snow melting or boiling for water treatment; even an over-night trip dictates a HX pot.

You might be able to put a collar around your pot with the neoprene cozy above that. But then you are adding weight without the weight-saving benefit that a HX offers.

Canister stove: get a HX pot.

Wood Stove: use your sock as a pot holder.
