I would like to introduce you to a new product that I absolutely love and carr with me everywhere now days. Not only do I carry the HydroBlu Versa Flow Water Filter n my Go Bag, I now carry this as part of my everyday gear. HydroBlu is back at it again with a great portable, pocket 3 Stage Straw Water Filter. This is not much bigger than a Sharpie Pen and can easily be carried in the front pocket of a button down shirt. Super lightweight and perfect for EDC Gear for on-pers
