You almost never see anything made from just kevlar - it nearly always has a layer of carbon on it for the simple reason that it's impossible to finish a pure kevlar composite off, unless you have a lot of gelcoat on it. Why? Because you can't sand Kevlar - it just goes fluffy :-) How are you going to do the neck? Again, you can't really machine kevlar easily.

This group tends to shoot ideas down pretty quickly by spotting flaws so I am posting this.... What if I wrapped a coolant bottle in kevlar using a fiberglass epoxy to strengthen it and protect it from heat?
