The 58 mug is definitely one of the most bomb proof bits of kit ever.Can't believe no one's mentioned the 58 mug yet.
Those buggers are built like the proverbial.
Admittedly, mine isn't 30 years old (it was bought new about 10-15 years ago), but I reckon it will outlive the planet.
Dammit, I reckon I could build a whole city with it.
And it'll still be good to go.
from my experience, due to how thin they tend to be they heat stuff up quickly but also lose heat quickly. If you dordle when taking a sip expect a burnt lip! to be fair I've had that from steel too.At Amazon somewhat misleading: "Good heat transfer performance". Realtive to what? Ti has slightly better heat conductivity than stainless steels but grossly inferior to Al.
I think the same happens with all metal cups, Al is the worst in that respect. Actually high heat conductivity means that vessel will lose heat quickly. Thinness means that it has low capacity for storing heat.If you dordle when taking a sip expect a burnt lip! to be fair I've had that from steel too.
