Yes FL, they are stainless! I meant that!
The brushed ones are dishwasherable. The painted ones aren't because the dishwasher can be so abrasive that the paint can apparently chip a bit.
I can only vouch for the 3.0 spout. It is such a good high flow. They have a lid with a cap too, but I don't know if its silicone and I don't know if it is as good to drink out of.
I only know all this because I spent ages researching one for DH.
