Best double-walled coffee cup

[wondabar]

I have bought a number of double-walled coffee cups from TK Maxx and they tend to end up leaking through the double wall, possibly due to the heat of the water.
Can anyone recommend some good-quality double-walled cups without handles and of a decent size, to fit lattes.

Chilly's are good.

Yes, and they come in 500ml, so is that about right size-wise?

I got given one of these and it was so good that I bought another for work.
It keeps my tea roasting hot for ages, to the point that I add some cold water or only par-boil the kettle. Even with these efforts to cool it to a drinkable temperature, it remains a good, hot drinking temp for 90+ minutes.

Beast Thermal Cup (Amazon)

My friend has Yeti mugs which we use on days out. They are marvellous. Keep tea piping hot & are nice to drink out of/hold. Also a great size for putting in car drinks holders (I find a lot are top big for this).

Is it a thermal cup or an every day drinking mug you want?

If it's the latter, I have these, that are perfect. They're pretty sturdy and have never leaked

Thanks for your messages. @NailsHairNipsHeels it is the clear cups that I am after, like the ones you describe. They have got those make before and they have leaked. So looking for something similar but more sturdy!

Ah that's a bummer I've had mine for about ; years and they're still going strong
I saw some in ikea the other day and they were a good size and sturdy looking £10 for2

Thanks for the Ikea tip. I'll give them a try. Maybe my water is too hot but the glass in the Amazon cups seems to crack after a while and water seeps through
