The Ultimate set up for ultralight backcountry water filtration. Take pump for a quick run or the full set up for overnights and bring 4 Liters with you if needed. 

  • Versatile water filtration system for hiking or backpacking
  • Can be utilized as a pump-action filter or gravity-fed system
  • Includes hollow core water filter that is field maintainable
  • Eliminates protozoa, bacteria, and particulate matter
  • Item #CAS00CJ
Eliminates: bacteria, protozoa, and particulates

In addition to the gravity system, one can use the filter alone for quick hydration straight out of any water source. So, if you are a trail runner or ultralight backpacker working in a very wet place, theoretically you could get away with using the 5.2 ounce (claimed weight) filter alone without bringing the extra hosing and the “dirty water” and “clean water” Dromlite bags. 
FULL INFO
MSR's Trail Base Gravity Filter System doubles between long-haul backpacking trips and fast-and-light trail runs when frequent water sources don't require you to carry a whole lot of water. When you're backpacking, set the reservoirs up as a gravity-fed purification system by placing the full dirty water reservoir above the clean water reservoir and letting the hollow fiber filter and gravity do the rest. When you just need a quick 20 ounces to get you through your hike or trail run, simply place the hose in a water source and pump the filter into your water bottle to quickly filter out bacteria, protozoa, and particulates.
