I am giving this 3 stars because of the lack of ingenuity in design. I'd expect Sawyer to make this a more streamline product as far as storage and packing goes. It's bulky when it shouldn't be, because of the accessories. Where it could take up 1/3rd of a pocket, making my adventure bag more comfortable to carry, it takes up a full pocket. This is a minor thing, and yet for someone that takes hiking/backpacking seriously it is a big deal. For my first Sawyer purchase I'm a bit disappointed,. It also feels cheaply made, I wont be surprised it it breaks easily. So be careful when using it.
Its, mini, very light, and SO cheap! its a filter that lasts for 100,000 gallons. Im so happy I picked this up and added it to my gear! :)
