Please recommend a tumbler that keeps you warm

I'm using something that came with a free gift when I bought it before.

I'm not satisfied with its thermal performance.

What kind of tumbler is there that keeps it warm?

I hope it focuses on performance rather than price

Please recommend me.

I've used Stanley Thermos a lot
I think Thermos is better if you just look at it
It's easy to use
