How long will the WATERSY gallon jug keep my drink cold or hot?

The vacuum-sealed double-wall construction plus a honeycomb-insulated lid extends temperature retention significantly. Expect cold beverages to stay chilled for up to 48 hours and warm drinks to remain hot for up to 24 hours under normal use.

• Double-wall vacuum insulation minimizes heat transfer.
• Copper-lined interior enhances temperature retention.
• Honeycomb thermal layer in the lid increases cold retention by ~20% and heat retention by ~10% over single-layer lids.
• Wide mouth reduces heat gain when filling with ice or hot liquids.
