GSI Outdoors Glacier Stainless Vacuum Bottle

When preparing to take the Siberian Railroad, from Russia to China, I read that insulated bottles were in the need to import. Food dining car was way overpriced, but each train car was free of boiling water on tap – means passengers will be able to make your own tea, instant noodles, or even hot chocolate. I ended up taking the tank-like Thermos King of the Jar to keep my hot water.

Looking back on my Siberian adventure, maybe I should have gone for the GSI Outdoors Glacier stainless water bottle reviewed by EZINESPORTS. The towering bottle feel bullet-proof and can keep the 1 liter (34 oz) of fluids warm or hot for several hours. The CAP even doubles as a cup, and keep everything within the drain for free–all ytin this is stylish, albeit large, design.


  • No condensation
  • Lid doubles as a full sized cup
  • Sustainable
  • It does not have to be removed completely, in order to cut down water, preventing the content exposed to cold or heat
  • Non-slip base
  • To keep food or drinks hot or cold for several hours
  • Vacuum insulation to keep the contents cold or hot for several hours
  • Stylish design–love the color choices, as well as
  • Odorless and tasteless stainless steel interior
  • Do not hold onto odors or flavors

After making chocolate a thermos and holding it there for about 12 hours, I was expecting a thermos bottle to stick with the smell for a few days. I was in the wrong.

Clean the bottle, I poured some hot water, screwed the stoppari, then shook the bottle. After the play, that a couple of times, chocolate taste/smell was completely gone, not SOAP.

In contrast to the cover-cups the other insulated bottles GSI Outdoors on the cover the Cup is almost full-sized cup. The Cup has been isolated too, so even if you pour boiling water in it, you won’t burn your hands.

Tip: the user manual recommends “main” bottle to make it warm before you put the drink include:

before use, the prime thermos bottle by filling with hot (hot drinks) or cold water (cold drink) and let stand for 5 min. pour out and immediately replace the water with desired beverage.

One of the toilunäkökulma which I thought was really cool was that the stopper is notches, so that you can pour the water out of the thermos bottle without completely turning it on.

You are the best out of hand washing this bottle and the instruction manual States “dishwashers can prematurely age the components”.


You can test how long you can keep the content of the GSI Outdoors thermos for hot, I primed it, filled it to the brim with boiling water, then place it in the freezer.

  • 10:00 AM–will be placed in the freezer for 1 liter of just boiled water
  • 1:00 pm (3 hours in the freezer)–I checked up out of the water, took a thermos bottle out of the freezer and tried to rotate the first Cap.It was frozen shut–I was previously screwed the CAP when it was still wet. After a bit of shaking and twisting, I got the cap removed.

Then I removed the main valve and poured the water into the Cup. Even though the outside of the vacuum bottle was ice cold, the water was steaming and too hot to drink.

GSI Outdoor thermos at 1:00 pm the Prime Minister. I used a medical thermometer to test the water, meant usually a measure of the body’s heat. The thermometer of melted–so the water was much higher than the 100 °

The water was still steaming

  • 4:00 pm (6 hours in the freezer) – I checked up out of the water before I went out for a run and it was still hot – hot enough to burn your tongue.
  • 8:00 pm (10 hours in the freezer) – By 8:00 am was about 2 cups left in the bottle.The water inside was still very warm and still steaming.
  • 10:00 am (12 hours in the freezer) – the water was not veryhot, but warm.I left the GSI Outdoors thermos bottle in the freezer for the night, was about 1.5 cups of water left.
  • 8:00 AM (22 hours in the freezer) – After 22 hours in the freezer, I opened the Bottle to check the water.The CAP was freezing cold, but when unscrewed the plug so that the water was still liquid – it had not yet come to the same temperature as the surrounding (below the freezing point). In fact, the water was at room temperature, I’d imagine about 70 ° F. It was not the cold, it was not warm either.

My test was unscientific, but the results were still pretty impressive. A rough estimate is that the water went down to 140 ° F during the 22 hours:

[from temp.] 212 ° F – 140 ° F ≈ 70 ° F [end temp.]

so about 6 degrees per hour (assuming that it went down at a constant speed):

140 ° F ÷ 22 hours ≈ 6 ° F

Chances are you would have stopped the drink within 12 hours, so you should have no concern about the drinks becoming cold, even if you are on a subfreezing.

Packaging Bottle is an icon image that can be used to keep liquids hot or cold for 30 hours. I assume that this means the time it takes to complete the flask of boiling water reaches the temperature of the surroundings.


  • 1 liter can be a bit too big for one person
  • Will not fit on the Cup holder
  • A little heavy, if you’re traveling light (23.5 oz) – considering how a big vacuum in the bottle, it is light, but if you’re traveling light, you probably do not want to take any of the thermos bottle at all.

If you are looking for a personal bottle to take to work or school, you can go to the 0.5 liter version. The 1-liter bottle can be a little too big and bulky – unless you’re really thirsty.

Compared to my body, you can see the bottle is pretty big.

The base of the 1 liter of Glacier stainless thermos is broad and sufficiently stable may be shaky camp tables, but it means that it does not fit in the average car Cup holder.

In order to limit exposure, GSI Outdoors insulated bottle is quite narrow. You will not be able to push your hand, so if you need a scrub, you will need the special cleaning brush. If your thermos is very dirty, use a guide suggests cleaning with baking soda.


The GSI Outdoors Glacier stainless thermos bottle is ideal for campers, adventure travelers and anyone who wants to keep drinks hot for a long time.

You can find the 1 litre version of the retail $35 and 0.5 liter version for $30.
