My husband has been gathering supplies for his first backpacking trip and one necessity is a water bottle filter. With the Grayl water bottle portable filter he can drink from streams and rivers! This bottle removes not only particulates and toxins but also bacteria, viruses, protozoan cysts, and parasites. Perfect for backcountry camping, travel to other countries, or just making water taste better in hotel rooms and Airbnbs on road trips.Find out more here: https://www.kitchenstewardship.com/grayl and save 10% off your first order!We received this Grayls filter for free to review, but our review is our own honest opinion!
