Katadyn: Katadyn Exstream Purifier Bottle

Designed to fit in most bike water bottle cages, the Katadyn Exstream Purifier Bottle features an internal EPA-registered Virustrat cartridge and carbon filter to remove microorganisms and all viruses from any water source. This 26-oz. bottle weighs less than the lightest backcountry microfilters and doesn't require pumping, making it perfect for extended mountain biking 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.
