Sawyer Squeeze filter
The Sawyer Squeeze is an excellent ultralight filter. At 3 ozs, it adds very little to any pack and had endless options. When we first switched to the Squeeze filter for our 3 season trips, we noticed the lamination separating from the bags and the bags began to fail.
To mitigate the problem, we modified our largest bag to be used as a gravity filter. While the Squeeze is slower as a gravity filter, the weight savings and reliability more than make up for the wait time.
There are much simpler ways to do this, such as using tape, but we wanted to make the modification as reliable and clean as possible.
