Using it away from home

  • Fill at the sink before you sit down. Hotel taps run warm after a few seconds.
  • In a public restroom, fill the bottle at the basin and carry it into the stall.
  • On the road, a bottle of drinking water refills it. Cold water works. It is only less pleasant.
  • Shake the bottle dry, pull the nozzle off and pack the two parts apart so they air out.

At the airport

Fly with the bottle empty. A carry-on liquid may hold 3.4 ounces at most, and both HappyPo sizes hold more, so neither passes the checkpoint full. Empty, the Original weighs about 3.5 ounces. Fill it at a basin after security or at your hotel.

The checkpoint rule in full, with packing tips

What it will not do on a trip

  • It does not heat water. In a cold climate, fill from the warm tap.
  • The cap sits tight. Open it by the coloured body, not by the nozzle.
  • A full bottle in a packed bag can press open. Travel with it empty.
