I’d recommend Thermoflask. I’ve had a pair of these for I dunno 7-10 years possibly, and from a quick search it looks like they may be sold in the UK. https://mythermoflask.com/products/thermoflask-insulated-stainless-steel-4-lid-combo-pack-40oz-1-1l-2-pack I believe they fit all your criteria and are “wide mouth” universal lids (have put some on from Klein Kanteen and others)

I know it’s semantics but those sound like nimby liberals and not progressives. Also yeah interesting argument on this part. I think easy climate action always starts in our homes and backyards!

“Resigned”

It’s been twenty degrees above average in Arizona this week. Should be frigid with snow on the ground (in the mountains) yet I was riding my bike with a t-shirt this week.
