Looks great but surely if this is to be kept out in sunlight to charge then your water is gonna get really warm.
Valentino, London - 20th April 2007
Firebox says: Good point Valentino, few ways around this one. You could put the Lightcap in the flask section of a backpack, using a elasticised pocket on the side of the pack – this will stop sunlight warming the water (as it’s covered) but charge solar panel. Or maybe use a drinks sleeve or even a thermos sleeve? This will keep your drink at a ideal temperature – this again will expose the top of the lightcap and not the drink to the sun for torch like goodness when it gets dark.
