In the current times of cooler, tumbler and thermos wars, there continues to be new thermos style bottles on the market. As an avid hiker, kayaker, camper, and fisherman, I am always on the lookout for a thermos with the ability close tightly, maintain the temperature of the contents, and provide a lid doubling as a cup. The GSI Outdoors Glacier stainless one liter vacuum bottle does all of this and more.
The GSI thermos is available in five color combinations, and comes in half or full liter sizes. This is not your father’s thermos. The GSI bottle maintains internal temperature for about 24 hours. The advertisements claimed thirty hours, but after weeks of use I decided 24 hours was optimal. At the 18-20 hour mark, hot liquids became warm.
Unlike various different thermos models the GSI vacuum bottle does not drip or leak when trying to poor a beverage. My old thermos would poor down the side when I tried to use it. The GSI vacuum bottle seals easily providing the user piece of mind when throwing liquids in a day pack.
The cup/cap design consists of a stainless steel liner coupled with an insulating plastic exterior to protect hands, lips, and flavor. The bottle has recesses on the sides to assist with grip so you don’t accidentally drop it in the water when on the kaya. There is a no skid pad on the bottom to prevent sliding and to cancel noise when setting the bottle down.
GSI Specs
The bottle weights 23.5 oz. when empty, and is easy to clean. The 18/18 stainless steel interior maintains purity. The half-liter model is $30 and the full liter is $35.
All and all this is my new go to thermos when chasing catfish at night, taking ice on a long trek, or hauling home brewed coffee on a long car trip.
