Grayl Ultralight Water Purifier
The Grayl Ultralight operates similarly to a French press, letting you fill it with water, plunge the filter down, and drink without worrying about 99.99% of bacteria, viruses, and debris. Based on a simple award-winning design, this water bottle saves you the trouble of packing lots of drinking water during a thru-hike or short excursion by letting you purify river or lake water as you go, and its replaceable filter is rated for 300 uses. It also doesn't need batteries, UV lights, or a complex filter or straw system, making it an ideal choice for anyone who needs to pack light and be certain their gear will do its job.
