Reply to comment by bradkrit in My collection of US Made Stanley Aladdin vacuum bottles. Left to right: 2001, 1989, 1969, and 1990. All still work flawlessly. by Psnuggs

All of these have been tested by me to -30°F (-34°C) ambient with wind and have kept coffee hot for at least 8 hours. In warmer temps and coffee is too hot to drink from morning to night. I put ice water in them in the summer and even at 95°F (35°C) and 70% humidity they still have ice in them after 12 hours. To me that’s flawless.

-30°F is equivalent to -34°C, which is 238K.

That's good to hear, thank you for elaborating. I've heard mediocre reports on reddit and some websites so I'm happy to hear your experience is good!

Keep in mind that these are the older US made versions which appear to be made better and of higher quality materials. From what I’ve read, there’s also charcoal in the walls which make them much more robust. They don’t do this anymore. That’s why new ones are much lighter than the old ones.
