i found their kickstarter video on Youtube as part of a collection of new camping gear. I was wondering if anyone else has heard anything about this. According to the video, this thing weighs 10.9 oz and claims to filter 16 oz of water in 15 seconds with their filter plunger. It does look kind of large and bulky, but would something like this be a feasible to take on the trail?
