Product review: Boulder Triple Insulated Stainless Steel Water Bottle
EcoVessel stainless steel bottle has a insulated stainless steel body and cap. The cap can be either totally removed or opened to reveal a drinking spout. The drinking spout is not a sports cap, it is just a fairly large opening with a plastic edge. Because it is large it is easy to drink from. The cap forms a good seal and does not leak.
This is a thermos bottle. Its construction is two stainless steel walls with a vacuum between them. This construction is similar to the old glass Thermos bottles with steel replacing the glass. The thermal conductivity of glass is lower than steel so the glass thermos keeps the temperature better, but stainless steel is unbreakable.
To answer the question how well EcoVessel thermos keeps the temperature I filled it with hot water and measured the temperature several times over 20 hours with a temperature probe. My temperature probe shows both time of day and temperature, in the table below I am rounding the hours but you can precise times in the video if you care.
★ start ~~~~~~~~~~~~~~~~ 185 degrees
★ 8.5 h later ~~~~~~~~~~ 132 degrees
★ 20.5 h later ~~~~~~~~~ 102 degrees
EcoVessel thermos holds the temperature well, on par with my favorite old thermos.
The bottle holds 20 oz of water and weighs 12 oz when empty. The bottle's base is 2 7/8" across at the base. This bottle fits into the bottle holder of my car. The bottle is 11.5" tall (from the base to the top of the cap). One unique feature of this bottle is that include a stainless steel strainer, so if you want use the bottle to brew tea or keep the ice from touching you lips the strainer will do it.
The instructions say that this bottle should NOT be washed in the dishwasher and hand washing is strongly recommended.
