O06 Eco Bottle 750 ml screw cap
If the original 1L size is too strapping, and the 500ml size doesn't even begin to quench your thirst, here's a 750ml size, which is 24.3 cm high.
Comes with a screw cap in peacock blue and, while stocks last, in margarita green too.
Here's a great little film from Tupperware Malaysia about the features of the Eco bottle range. Sadly I can't get you the strap-on version, just the bottles themselves.
