Its primary benefit is the impressive double-walled vacuum insulation that maintains heat for up to 12 hours and cold for up to 24 hours, though its 750ml size may be slightly bulky to pack in smaller, lightweight daypacks.

No, it is recommended to hand-wash the flask to preserve the vacuum seal and the integrity of the insulation.

Yes, the double-walled vacuum construction ensures the exterior remains condensation-free and cool to the touch, regardless of the temperature inside.
The flask is constructed from high-quality, durable stainless steel.
A long-handled bottle brush is recommended for cleaning the interior walls to prevent buildup.
Ensure the stopper is screwed on tightly and the gasket is not pinched or damaged. Pre-heat the flask with boiling water before filling.
Check that the twist-and-pour stopper is fully closed. Inspect the silicone O-ring on the stopper for debris or misalignment.
Ensure the exterior of the flask is dry to provide better grip. Do not over-tighten the lid when closing.
To get the most out of your flask, it is recommended to rinse it thoroughly with warm, soapy water before the first use. Always ensure the twist-and-pour stopper is firmly tightened to maintain the vacuum seal. For cleaning, avoid using harsh abrasives or steel wool, as these can damage the finish. Because the unit is vacuum-insulated, it is strictly recommended to hand-wash only; placing it in a dishwasher can damage the seal and compromise thermal performance. Store the flask with the lid removed when not in use to allow any residual moisture to evaporate completely.
