In addition to high heat retention, the second model of the Stout is lighter and more portable

The Vacuum Vacuum Flask Stout has undergone a minor change. In addition to the weight reduction, new colors have been added. The popular style has been continued as is.


-60g lighter than the previous model

By reducing the thickness of the stainless steel bottle, we have made it lighter. It is 60g lighter than the previous model. This is a steady improvement like wringing out a dry rag, but it is actually very significant because it improves the heat retention efficiency.

-Coffee brewed in the morning stays hot until evening

The inner walls of the vacuum part of the stainless steel vacuum bottle are coated with copper to prevent heat transfer due to radiation. In a test with boiling water, the temperature remains above 74 degrees Celsius even after 6 hours, showing its high heat retention effect.

-Integrated structure to prevent loss of the lid

The bottle and lid are connected by an integrated silicone strap, which prevents the lid from being dropped or lost. The silicone strap is strong enough to hold a carabiner to attach the bottle to the bag.
