Snow Peak says:
The Gold Standard of camping mugs, this double-walled, insulated titanium mug will keep your coffee or tea warm nearly all day and is built to withstand any adventure without adding weight to your pack. Folding handles make the mug easily packable.
Double-wall titanium should not be used for cooking or placed over a heat source.
*Please note – to preserve the printed logo on your mug we recommend you wash the item by hand, dishwashing may cause the printing to loose adhesion and come away from your mug.
