My hiking bottle for many years was a Takeya. The plastic lid broke on me but you can replace that without having to replace the whole thing, overall I've been satisfied by it.

I actually replaced it with a used Stanley based on advice from a forum post, lmao. Get one from before 2007 which is when they changed the design and made it flimsier. If it says "made in Tennessee" on the bottom then it's definitely one of the good ones, they go for super cheap on eBay because they made millions of them for forty years and they're all practically indestructible.

i had a thermoflask till the cops stole it. it did its job.

Thermos Nissan from a Goodwill. For some reason they usually have one.

$2 and very good.

Klean Kanteen TKWide for cold, TKpro for hot.

The TKwide can do hot as well with a cafe lid but will let in more cold air than the pro
