    Multi-sport water purification.

    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.

    • 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

    • Familiarity: I've used it several times

    I owned a few MSR Drom bags a few years ago, black and the drom lites... I could never get rid of that funny taste in the water. I sold them and went with Platypus bags instead... no issues. I love MSR products and the Gravity "Autoflow" is awesome, never had an issue with taste in that big red bag so I purchased this Trail Base setup... and they have that funny taste! I thought MSR would have addressed this by now. I will be trying (again!) several ways to get rid of it. Last time I tried a lot of different things... baking soda, Aqua-Sol and even Vodka but nothing worked. I hope these will be better but I don't have my hopes up.
