Description:

These flasks feature an internal double-walled design, with an airless layer between the two walls. This layer prevents the convection of heat in or out of the flask, keeping the internal contents at their perfect temperature for longer. A reflective internal wall also works to minimise heat loss by radiation.

All Grunwerg flasks have an ultra secure lid, which when closed forms a secure, airtight seal. Not only does this prevent heat from escaping from the flask, it also allows you to store it horizontally in a backpack or bag without leaking.

A study by the Cutlery & Allied Trades Research Association (CATRA) found that Grunwerg products retained heat longer over a four- and eight-hour period when compared to three top competitor products.
