Review on Pack Water Filter Straw Backpacking Outdoor Recreation for Camping & Hiking by Wayne Espinoza

As far as water purification goes I was concerned about these straws as the price is much lower than the competition but I can tell you they look, feel and as far as I can tell, work like all the others. A big win for me was that they arrived in thick, individually sealed bags that can be ripped open and resealed, which is great for a gift to a friend as they don't have to wonder if it's new. Also great for throwing in kits, bags, stashes or whatever it is called. For the price of these straws you will never be without drinking water.
