34-oz. water bottle with high-volume EPA registered purifier to kill viruses and bacteria.

Created specifically for hiking backpacking and remote trekking the Katadyn Exstream XR Purifier Bottle features an internal EPA-registered Virustrat cartridge and carbon filter to remove microorganisms and all viruses from any water source. This 34-oz. bottle weighs less than the lightest backcountry microfilters and doesn't require pumping making it perfect for extended day hikes and summer mountaineering around questionable water sources. One thing to consider is that the filter and cartridge require a bit more work than sipping from a standard water bottle--but the extra safety measure will keep you healthier miles beyond the nearest trailhead or outpost.
