In addition to high heat retention, the "Stout" second model vacuum thermos stout, which is lighter and more portable, has undergone a minor change. In addition to weight reduction, new colors have been added. The popular style continues as it is.

■ Weight reduction of 60g compared to the conventional model We have reduced the weight by reducing the thickness of the stainless steel bottle. It is 60g lighter than the previous model. Its a steady improvement like squeezing a dry rag, but it also has the advantage of improving heat retention efficiency, which is really significant.

■ Coffee brewed in the morning is hot until the evening. By applying a copper plating coating to the inner wall of the vacuum part of the stainless steel vacuum bottle, heat transfer due to radiant heat is prevented. As the result of keeping the temperature of 74 ℃ or more even after 6 hours in the test of adding boiling water, it shows high heat retention effect.
■ Integrated structure to prevent the lid from being lost The integrated structure that connects the bottle and the lid with a silicone strap prevents the lid from being dropped or lost. The silicone strap is strong enough that you can set the carabiner and attach the bag and bottle.
