People that stacked Lifestraw
Clean water is essential when traveling. As a world traveler, I know first hand how important it is to have a water filter to ensure you don't get ill with waterborne disease. I always have one at hand wherever I go internationally.
If I were stranded on an island... I’d bring a Lifestraw because it’s possible that I can rely on the island supplying food and resources to create tools but I can’t rely on it providing clean water. And clean water is kinda necessary for survival.
