Hydration Bottle – a printed hour scale that paces your water

Heat-resistant glass with an hour scale printed up one side. The screw lid seals, so the flask travels in a bag beside a laptop without soaking anything. Two sizes: 500 ml and 750 ml.

Why choose this hydration bottle?

Glass has no memory. Last week's cold brew leaves nothing behind in it, which is more than can be said for most reusable bottles. Add the printed scale and the flask becomes its own pacing device, with no app and no notification.

• Printed scale: hour marks run up the side, so one look tells you whether you are ahead or behind.
• Thermal tolerance: the glass takes hot tea as readily as iced water.
• Screw-top seal: the lid threads down and stays shut in a packed bag.
• Clean flavor: nothing leaches in or out, so every drink tastes like itself.
• Size choice: 500 ml keeps a desk tidy, 750 ml covers a long afternoon.

Fill it once in the morning and the rest sorts itself out.

Wash it with warm water and a soft bottle brush; scouring pads will eventually take the printed marks off. Let the glass adjust between extremes rather than pouring boiling water into a chilled flask. Dry the thread before you close the lid and the seal holds better.
