GravityWorks 2.0L Water Filter

This is the water filter I've used for over 4 years and it's been one of the best backpacking purchases I've made. When you are hiking for hours, the last thing I want to do is pump water into a bottle. This just lets gravity do the work and it's incredibly fast. When camping with a group, this fills everyone's water bottle in minutes. Just can't beat the convenience and efficiency.
