GSI Outdoors Stainless Vacuum Bottle

This thing is big, at least a lot bigger than I was expecting when I looked at the picture. The stainless steel design is easy to clean and maintain. But most importantly, it keeps the warm liquids warm. I filled this thing up Sunday morning with some hot chocolate in below freezing temperatures. When I got home Monday morning and poured out the leftovers, it was still steaming in the sink. Keeps enough hot drink inside that me and 3 other dudes were able to all share a glass of some much needed hot stuff in 10 degree weather.
On a side note, here's a recipe for some delicious camp hot chocolate.
3 packets hot chocolate mix
12-17 Andes mints depending on how strong you want it
Mix and drink up.

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!

I went ski touring 2 days in a row and used this GSI Vacuum bottle one day and a Hydro Flask the next. The GSI offered infinitely superior heat retention when compared to the Hydro in basically the same conditions and temperatures. The liquid in the GSI botttle was literally still warm at 5 pm, whereas the Hydro Flask liquid was barely tepid. They both performed admirably during the first 3-4 hours, but if you are going to be out all day I would recommend this bottle first. It was able to retain heat much longer than the Hydro Flask when I tested both.

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.

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...

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!

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.

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.

I gave this as a gift but he said, "this thermos will keep your tea hot for an entire 7 hour tour. Not warm but hot! Such a morale booster after a long day in the mountains."

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.
