A crucial item to have with you in any scenario

I had been searching for some time, for a really good and effective water filter to take on my expeditions.
The Water-to-Go filter system allows me to collect water when I am on the move. It does not have to be fresh water, it can actually be water from lakes, dirty rivers and even puddles. The reason it is ahead of the game and why it will be with me on all my expeditions: There is no pump action needed, no need to boil the water and no need for water purification tablets. You can top it up on the move and go ahead and drink it straight away. A crucial item to have with you in any scenario. Fantastic product, team & service, I highly recommend.
