LifeStraw

LifeStraw originally began as a humanitarian drive to give people in developing countries access to clean drinking water, wherever in the world they are. Nor have they lost sight of that - but these days, their products are being used by intrepid explorers and everyday adventurers alike as an insurance policy against dehydration in the great outdoors. From lakeland tarns to grassland streams, every body of water you encounter is ripe for drinking from, thanks to the simple straw in your pocket.

Plus, LifeStraw are actively battling climate change through their Carbon Credits scheme - every credit purchased represents a reduction of one tonne of carbon dioxide emissions from the atmosphere, and one year of clean drinking water for a family in Kenya.
