I am trying to find a coffee cup that will hold a bit of heat, and not make the coffee taste like metal. I am not thrilled about putting really hot stuff in plastic, but it is not microwaving it, so that is something. I tend to brew with either a funnel or an aeropress, and will make it one cup at a time. Whats in your drybox/kitchen box or drybag? and hopefully it will fit in a cup holder for shuttle runs too
