Simple filter for easy clean water
I dig the Grayl system and this filter is simple and easy to use. Follow the instructions carefully to avoid contamination but it functions as expected, just twist it onto the inner bottle and press the inner bottle into the outer bottle to filter the water. Easy fast and convenient. It adds piece of mind when drinking anything from tap water to spring runoff and is a great adaption to any travelers gear bag.
