Overview: Glacier Stainless Microlite 500 Vacuum Bottle

Drinking is critical. We of the outdoors globe know this, which is why so several water bottles and Camelbak-style bladders are sold to us each and every year. We have several options of containers from which to sip and slurp our beverages of choice.

Enter the Glacier Stainless Microlite 500 lightweight, packable vacuum bottle. This is a nice-looking drinking bottle that stays slim even though providing the insulation benefits of a stainless steel vacuum bottle (believe Thermos, Yeti, and so forth). In my experience, it insulates quite well… but it is not that wonderful to drink from, and it demands a far more-secure latch.


  • Double-wall stainless vacuum bottle keeps cold stuff cold and hot stuff hot.
  • Flip-top lid signifies there’s no parts to shed (like a thermos lid/cup, for instance).
  • Slim design and style indicates it fits water bottle pockets/holders on packs and such.


  • Made in China.
  • Requirements a far better lock for the prime latch — it flooded my hunting pack with hot coffee.
  • Dispenses slowly you can not get a very good hearty swig.
  • Cleaning can be a hassle.

My Overview

I was favorably impressed when I received this bottle, and I liked the flip top and its lock, and the general top quality. So I took it apart and washed it up according to directions, which is not a huge deal but a bit of a hassle. “Always separate and clean lid spout, O-ring, and stopper seal,” says the directions, and in the finish you have four parts of the lid to wash, keep track of, and reassemble.

When the time came for a road trip to Colorado from Florida and back, I grabbed the GSI bottle. And it kept my soda cold for a good whilst, but somehow I constantly wanted far more of a swig than the little dispensing hole gives. Bummer.

Later in the trip, my buddy stepped on it… let’s just say that it won’t stand up to 250 pounds. Oops! But I got a replacement simply enough.

In further testing, I found that I nonetheless didn’t consider it dispensed beverage rapidly sufficient — but the final blow came when I filled it with coffee one particular cold morning, cautiously locked the lid shut, slipped it into my pack and headed to a deer stand to hunt.

Now, this wasn’t a lengthy hike probably significantly less than 200 yards. But when I got to the stand, I opened my pack to discover the bottle’s lid hanging wide open, half of its contents possessing been dispensed onto every thing inside of my pack.

The most woeful loss was my rangefinder, which thereafter refused to operate. Argh!

As I said, that was fairly much the final blow. A drinking bottle that won’t supply me with a good mouthful of my drink — but which will open itself and spew all more than my gear — is simply not for me.

That mentioned, it does have excellent insulation properties, and I identified it to stay cold or hot just fine.
