In reply to Xharlie:
> I've tried plastic... but I'm pretty vehemently anti-plastic, these days, because of the taste and because I just hate the idea of pouring boiling water into it and consuming the result.
> I've tried cheap, thin stainless. This seems ok. At least you can use the mug directly on the gas if you're alone, saving the need to carry pots.
> I've tried insulated stainless. These don't suit me. They are completely impractical if you are on the move - the rest of the party has upped and gone before your tea is quaffable. And you lose the other benefits of stainless because you can't cook in them.
> I've tried aluminium - these are abysmal. The thermal conductance is way too high. Your mouth may be used to hot tea - your lips are NOT! By the time the mug itself is approachable, your tea is icy. Also, apparently aluminium is terribly unhealthy - I do not know how true this claim is - I'm still alive.
> I haven't tried other materials (more modern synthetic materials, alloys or titanium wotsits) or designs. Things that are important to me are: no plastic parts, robust enough to survive many knocks and a proper handle - none of those silly half-half handles that flap about annoyingly and none of those 'L' shaped ones - if you can't clip a karabiner to it, it can't be hung off the back of your pack in an emergency.
> Suggestions?
Man up or try an indoor sport involving Staffordshire Chinaware?
