GSI Outdoors Glacier Stainless Vacuum Bottles

Kept coffee warm through my whole drive to Yosemite, then hot chocolate warm until dinnertime the next day! This thermos is far lighter than others I've tried, and it looks pretty sweet too. Definitely a good purchase.

Keeps your coffee or tea real warm after a day hitting the slopes, almost too warm actually. I usually leave the liquid cool down a bit before closing it. Haven't seen the construction issue other reviewers are experiencing.

Does the job it's designed to do and does it well. Keeps your drinks HOT and is spill-proof. Just toss it in and don't worry about it. Mine already has a couple dents in it, so the outer construction could be a little more rugged, but it still works perfect.

I have gotten this recently (1 L version) and it does the job. I was looking for something lighter (this is 600 g or 21.16 oz) but did not have time to continue my research. I would be using this also outdoor in cold temperatures (down to -30 C or -20 F). I would be comparing the performance of this bottle with the Nalgene Tritan/OR Water Bottle Parka combo (together they weight half of this bottle, 300g, cost a bit more around 34$ and are a bit more compact). Recommended use is clearly marked as "camping" so I cannot complain too much anyway. :-) I have also considered the Primus 1L but it was a bit more expensive and only a little bit lighter.

These are awesome! Fits well in a water bottle pocket on my bag. My coffee is still warm after a day on the mountain, and my bf loves it (keeps his coffee TOO hot). Love the pour spout so you don't have to let cold air into the bottle. Now my dad wants one too...

Thermos works good for what it is for-
Keeps my coffee hot all day at the crag and pours out a steaming beverage up to 8 hours later. I love it's simplicity but was disappointed when the bottom outer ring split open in two places after a few uses. It doesn't seem to affect its function so I probably won't send it back but like I said disappointing for a 'vacuum bottle'. Should be bombproof so we can all just fuhgettaboutit- After all, I'm not using it for tea parties in the flower garden.

I take a .5 liter of hot chocolate up with me to the mountain every time I go skiing. Drink the first half to warm me up before skiing and 6-8 hours later it is still hot for a nice warm up after skiing. Does not leak at all and the lid makes a nice little cup.

Awesome vacuum bottle! Keeps hot water/coco too hot to drink after 8hrs, even when stored in the freezer. After 36hrs, hot coco does just turn to warm coco....but that's still awesome when coming back from an extended climb.

Few complaints: The bottle definitely isn't light, so take that into account when looking at bottles to take into the backcountry or leave in the car. I would have preferred the inside of the cub/lid be stainless steel as well, but it's plastic lined. As others have mentioned, the inner lid is finicky, but easy to figure out with a few uses.

Definitely a great product. Love having it!

Build is quality and simple. I've had others with the push top and they are impossible to clean and have to many gaskets. Went hiking for a day and a half and came back to the car with warmish coffee for the drive home.

this thing keeps stuff hot hot hot for a long long long time.

you think: that's what a thermos should do! why is this joker only giving it 3 stars?

2 reasons:
1. the inner cap is not very strong and you really have to pay attention when screwing it in or it jsut over-threads itself and pops loose. not a terrible thing, just a slight annoyance.

2. after a few weeks of usage the seal (wherever it may be) broke and air with a tiny bit of liquid got in between the stainless shells. that means the heat gets transferred straight to the outside environment. and all you scientists out there know that means room temp coffee.

it was a great great great thermos... while it lasted

The glacier stainless steel vacuum bottle works as described. Keeps the coffee hot and washes up well. We pour in a spot of cream before the coffee so the washing up is very important. There are no "hidden" spots that harbor liquid, hence creating a spoilage issue with the cream. We are happy with the pot. Just wish it were a bit larger.

This kept my coffee hot for 8 hours at work
Great Buy!

I've had my Thermos for a few years now and haven't had any complaints about it. It keeps my Hot Water or Hot Chocolate hot all day at work and it's fun to open the vacuum seal and hear kind of vacuum pop noise it makes! I love my Thermos!

This is the best vacuum bottle I have owned, coffee stays warm for an entire day of backcountry skiing, and also works as an awesome coffee shop piece - sit around with your Mac in Boston, and you'll be the hippest person there - that is, if you remember to put your goat sticker from this website company on the bottle first!

I take this Thermos up on long tours, and keep it in my car on resort days. It keeps your tea, or Irish coffee hot, and steaming forever!!!!! A hot cup on Joe will stay hot for 6-8 hours in sub 0 temps. This thing is amazing.
