A few months ago I wrote about what has become my best hydration solution while fishing. For years I used to carry a water bottle, but then would run out of water, even while surrounded by a lot of fresh clean water. I drank from streams directly on occasion, but then tested positive for giardia (never had any symptoms).
So, I picked up an ultra-light and very small water filter made by Aquamira, the Frontier Pro. It was cheap, super light and easily fits in a pocket. To go with it, I found the Platypus 500ml water pouch to be the ideal companion. I had finally come my across the best solution for always having water with me but without carrying a lot of weight. It kind of changed my life for fishing.
If I’m on the stream pretty much the whole time I’ll carry just the filter by itself, pull it out and drink directly from the stream.
When walking any distance to or from the stream I’ll take the bottle with me. And, of course, this has become my go-to water bottle for traveling anywhere or using on a daily basis as it is foldable and slim, so it fits in my back pocket and reduces in size as I drink from it.
