This super-cheap lightweight plastic cup form IKEA has become a core part of my cooking and eating system. The cup weights 1oz, and is insulating enough to use for tea or coffee, as well as cold drinks.
It is also sized at exactly one cup measure, so can be used to measure water into your cook system. It fits perfectly into my small (0.6L) Ti cook pot, with my whitebox stove, fire steel, windscreen and orange lexan spork inside. All wrapped up in a brawny cloth (also orange) to provides a super compact cook system which doesn't rattle in my pack!
Best of all, the 6-pack of these cups retails for $5, giving an individual price of <$1 per cup... my wife is just wondering where the orange one went!
