These titanium insulated bottles are very light and easy to fit in any backpack.
They include a filter that works very well for larger leaves (pan fired green tea, cooked Pu Er, folk bancha...).
The bottles are also very useful if you want to shake some iced matcha on the go. Load the bottle very cold spring water (crushed ice is an option), add two grams of matcha and shake.
Please consider also our titanium gaiwan and cups.
