how long does this product last? 1 day? 1 month?

I used it for the first time this weekend. On a backpacking trip. I thought it was useful to have in addition to a filter pump to bring water back to Camp. It seemed well-made, how long it will last Would probably depend on how dirty the water is that you put through it ,if you clean it consistently and if you were careful not to abuse it. But I will get $20 worth of use out of it for sure. I expect it to last me for multiple trips.

Does it come with the bag?

Hi Mike, Thank you for your interest in our Water Filter Straw. Yes, the item comes with two bags. One is the blue gravity water bag which is used to fill with the raw water, another is white used to fill with the filtered water. They are connected via the straw to filter the water for drinking. If you have any other questions, please feel free to give us a call between the hours of 8:00 AM-5: 00 PM (PST), Monday through Friday at 1-888-352-3558. We will try our best to help you out. Thank you very much. Best Regards, Mia Lauren
