This is a really cool item I picked up for my friends birthday not to long ago and actually grabbed myself one to. It is a survival straw, yes you read that right a survival straw !
It can filter 1000 liters of water with it’s internal filter system, what a great handy easy to pack item ! You can use it like a straw and drink out of of river or lake OR you can fill up a bottle and use it as a straw that way as well.
You can only pack and carry so much water so being able to safety filter water as you need it is a “HUGE” survival plus ! ! ! !
