  • Inexpensive Water Filtering for Emergencies or Outdoor Excursions
Style: 4 Pack Color: Blue
I haven’t had to utilize these yet, but one of the things that drew me to them is I can screw a waterbottle to the straw and take it with me. I am not required to stay at the source to filter or drink water directly from the source. They are super lightweight and are made of durable polymer so they won’t crumble or break in a backpack. ... show more
