Whether you’re camping, doing aid work in a third world country or heading to a cheap South American resort for a carefree week, LifeStraw is a must. Basically an oversized straw with a 0.2 micron filter, LifeStraw lets you comfortable drink straight from potentially contaminated sources, helped by a high-flow rate and 264 gallon lifespan. Plus, it only weighs 2 ounces, making it easily pocketable – perfect for morning-after rehydration, gastro-free.
