With double wall vacuum insulated, outside of the bottle would not get cold enough and condensed; you are worry free from bottle sweat that may cause your desk or contents of your bag wet. No more sweaty palms while holding icy cold beverage!

Single wall bottles are not insulated and will therefore “sweat” when filled with very cold fluids. When air comes in contact with a cold non-insulated bottle it begins to cool down. If it cools, water vapor in the air is condensed and turns to liquid that beads up on the outside of the bottle

Not recommended.

The high heat in a dishwasher may damage vacuum seals in container. A damaged vacuum seal causes the vacuum container to lose its insulating function. We recommend hand washing to prolong usage life. Be sure to wash your product before first use.

We recommend cleaning your bottle and lid once per day especially if you drink something other than water to keep them mold and germ free.

Other than plain water, all kind of beverage should not be left in the container for longer than 12 hours.

DO NOT use strong detergent.

DO NOT use abrasive cleaners or scrubbers since they may dull the finish.

DO NOT use bleach or cleaners containing chlorine on any parts of the product.

For maximum efficiency, you can preheat or precool your vacuum insulated container with hot or cool water before filling with your desired beverage.
