I'm curious what options are out there for really light cups/mugs. In generally, plastic ones seem to be the lightest but I'm having a hard time finding one that isn't excessively large.
I used to use a GSI Mug that weighed 71g (2.5oz) and probably held 2 cups (1 pint). Being a single wall mug, you could never drink this much coffee before it was cold.
Yesterday I found a GSI Infinity mug at MEC for $2.80 that weighed 49g (1.8oz) and holds a bit less (14fl/oz or 1.5 cups). I bought it because $2.80 to save 0.7 ounces is great, but I still feel like there's gotta be something a lot lighter.
I think someone could probably make a mug around 1 cup (250ml) capacity out of BPA free plastic that weighs about an ounce (28g). Does anyone know if this exists?
There are also all the titanium mugs out there, but I'm not sure what the appeal is because the don't seem any lighter. The lightest Evernew mug holds 300ml and weighs 46g. That's smaller but not any lighter than what I have now.
