I was given one of your Water-to-Go bottles for my trip to the Pamir Mountains by Edge Expeditions. Great product. I used it every day for two weeks straight. The water in this area was highly likely to be contaminated. I drank 8-10 full bottles through the filter every day. That is a lot of plastic rubbish saved! It was very convenient to just dip it into a stream along the dirt roads. I did not trust the water even in the hotels in this remote part of the world.
Great call to use these filtered water bottles.
