Carbon felt cosy

A place to chat about gear and the philosphy of ultralight. Ultralight bushwalking or backpacking focuses on carrying the lightest and simplest kit. There is still a good focus on safety and skill.
Forum rules
Ultralight Bushwalking/backpacking is about more than just gear lists. Ultralight walkers carefully consider gear based on the environment they are entering, the weather forecast, their own skill, other people in the group. Gear and systems are tested and tweaked.
If you are new to this area then welcome - Please remember that although the same ultralight philosophy can be used in all environments that the specific gear and skill required will vary greatly. It is very dangerous to assume that you can just copy someone else's gear list, but you are encouraged to ask questions, learn and start reducing the pack weight and enjoying the freedom that comes.

Common words
Base pack backpacking the mass of the backpack and the gear inside - not including consumables such as food, water and fuel
light backpacking base weight less than 9.1kg
ultralight backpacking base weight less than 4.5kg
super-ultralight backpacking base weight less than 2.3kg
extreme-ultralight backpacking base weight less than 1.4kg

Carbon felt cosy

My latest idea: get a handle-less pot perhaps with a bail for convenience and make a cosy for it out of carbon felt. Carbon felt is highly insulative, light and heat resistant so you can leave it on the pot while cooking which should significantly reduce cooking times. It's pretty light too, about 22 grams for my 1.6L pot. The only question is can I find a connective material that also doesn't melt or burn. Also I need to find a titanium pot or similar that doesn't have handles.

Edit: apparently carbon thread is a thing so maybe that'll work. Probably hard to use, but hand stitching should work for this.

Hey Joomy,

In my brief experience using it as a windshield, the carbon felt doesn't actually like direct flame - it reacted a bit when it got too close.

OK just did some experimenting. Long story short, doesn't seem to be effective. Not because of the materials but simply because the initial hypothesis is flawed. I did a number of boils and the uninsulated pot boiled faster than the insulated one. My theory is it's preventing the heat from transferring up and into the sides of the pot. That said, the ambient temp is pretty high at the moment (around 20C I reckon). At colder temps the heat loss might outweigh this effect but I won't know for sure until colder weather arrives.
