MSR Trailshot Water Filters

From: £1.00

The Trailshot Micro Filter is a tiny water filter designed to be used to drink directly from the source and to refill bottles while on the go. With a flow rate of 1L/min you can quickly fill bottles and with its small size it can easily be stashed in a rucksack/running vest pocket or even a jacket or trouser pocket.

Easy one-handed operation filters one litre in a mere 60 seconds, so you can get back on the trail quickly and moving again.

Weighing just 142g, the TrailShot water filter is the ultimate filter for fast-paced, high-mileage adventurers, like trail runners, hikers, fast-packers and mountain bikers.

To use the Trailshot you simply drop the end of the hose into your water source and squeeze the filter container to force the water through the filter. Your clean water is expelled through the nozzle on top of the filter. It’s easy to clean in the field as it just require a few shakes to restore the flow rate should it drop. It will treat up to 2,000 litres before the cartridge needs replacing.

As it is a Microfilter it does not remove all water bourne viruses.
