"Fast, good and cheap; pick any two" is a choice we are usually faced with when buying trekking gear. Seldom do we come across a piece of gear that checks all these three boxes. Lifestraw is one such piece of gear. We heartily recommend the Lifestraw for three season hiking and trekking. In winters when you have to melt snow to get potable water, the lifestraw is not usable. But for every other trekking scenario especially in the Indian Himalayas, this is a must have item in your backpack.
