So, I got bored this weekend and needed something to work on. I had been looking at the Sawyer squeeze filtration system. Considering the price tag of nearly $60, I talked myself out of buying one. I kept thinking about it and realized I had enough stuff around the house to make my own; in fact, I think I can make it lighter.
Here is the stat I have to beat:
filter: 3.2 oz (used filter/already saturated)
