Does an insulated water bottle sweat or create condensation?

One of the biggest benefits of an insulated water bottle is zero condensation:

• Why Regular Bottles Sweat: Cold liquid chills the bottle surface, causing moisture to condense from air
• Why Insulated Bottles Don't: The vacuum barrier prevents the outer wall from getting cold
• Result: Your insulated water bottle stays dry at all times

This means no wet gym bags, no water rings on desks, no slippery grip. Our insulated water bottle keeps everything around it completely dry.
