Just trying to change things up to see if I like this better than my CNOC and Sawyer Squeeze that served me well on my AT Thru Hike. My one question, do I not need to worry about the larger Be Free filter freezing even though they are similar filtration methods? Have seen many comparison videos, but no one has mention freezing like they warn with the Sawyer. I often slept with my Sawyer but this could be a game changer for cold weather backpacking.
