No. This is single-wall steel — it's lightweight and doesn't sweat much, but it won't keep water cold all day or coffee hot for hours. If you need insulation, look at our Bamboo Vacuum Flask.

The bamboo lid seals tight with a silicone gasket inside. It won't leak when the bag is held upright. Don't pack it sideways with hot or coloured liquids — physics and gaskets only do so much.

Hand wash with warm water and dish soap. Don't put the bamboo lid in the dishwasher — the heat and humidity will eventually crack the bamboo. The steel body is fine to rinse and air dry.

Yes, but expect it to cool faster than a flask. Single-wall steel transfers heat. Good for warm water, herbal tea, or anything you'll finish in 30-60 minutes. Not the bottle for keeping chai hot the whole workday.

Yes — food-safe natural finish. Don't soak the lid in water for long periods and let it air dry after each rinse. Treat the bamboo lid like a wooden spoon, not a steel one.

Just the bottle and your hand. It's stitched through the bamboo lid for carry use — clip it to a backpack daisy chain, hook it on a desk hook, or loop it on your wrist.
