The 'popular' Stanley ones have a stainless steel vacuum flask inside them, your old Thermos brand's vacuum flask will be glass, and break probably the first time you drop it.
Dents won't crack the Stanley because they're not glass, they're stainless steel inside, they'll keep working fine.
Source; I've had this Stanley thermos since 1972, 50 years now, and it still works fine.

That’s an insult to the thermos brand ^/s

I still remember the day I broke the glass Thermos my dad had had since college. I had no idea it was glass inside, my 11 year old brain was blown

My vintage 60s Thermos King Seeley is stainless steel.

Do the glass ones keep temperature longer?

I dont know about longer but if you follow the preheating instructions and put hot water in them for a few min, dump it out and then put your hot beverage, soup or whatever inside. I get 8-9hrs out of mine if the coffee lasts that long lol.

Just to add on to this:
Think of a thermos like normal cup with a lid and a blanket wrapped around it.
The lid prevents hot air from escaping, hot air escaping makes room for more hot air and steam that then escapes, and the lid basically just keeps heat from escaping through that series of events.
The blanket (usually a gap of air between two layers of metal, but sometimes glass, sometimes styrofoam) does what blankets are made to do and doesn't transfer heat, so the heat inside the cup doesn't leak out through the blanket much.
This is what keeps your beverage hot - the fact that all the ways heat usually leaks out of it are sealed up well, so it takes a lot longer for the heat to leave the liquid. Same thing with cold beverages - the protective barriers of the thermos keep the heat outside of the cup from getting in.
This also means you can enhance any thermos or cooler with your own blankets. Literally wrapping a cooler in a blanket will keep the stuff inside cold much longer than any amount of engineering plastic into a layers of foam (which is basically how most coolers work - they use plastic foam as a blanket). Similarly, putting your thermos inside of a blanket will keep it better isolated as well. I have no idea how long you could expect to keep something hot, but with enough blanket you could conceivably get days out of it.

In my experience, no. A lot of the glass ones aren't even vacuum flasks.. A lot are glass over styrofoam. They existed because they were much cheaper.

Yeah i remember when Kids lunch boxes had the glass thermos bottles in them also... Dropped my new lunch box and immediately broke mine on the first day of school.

Yup. I remember the glass tinkling in several lunch boxes. The fear of having to tell my mom I broke another one!

In fairness, making something that kids are going to literally throw around on the daily out of GLASS isn’t smart product design. Hardly your fault!

That was their big ad push wasn’t it? That they “cannot break” or unbreakable something like that.

Damn, that bottle has seen things and been places. A world-weary veteran still turning up for duty.

I had a job driving the snack cart on a golf course. I decided to load up coffee one morning, in a big five or ten gallon urn. It exited the cart at some point, and that’s when I learned about glass thermos containers.

The make the most astounding glass shattering noise if you throw one up into the air and onto the ground but if the cap is still on it makes no mess
