MSR TRAILSHOT MICROFILTER £40
If you want the security of filtered water, but without the faff that this can sometimes involve, the TrailShot will do the job. Drop the hose in the water source, squeeze the filter and pump clean water, free from bacteria and protozoa, straight into your bottle or hydration bladder – or straight into your mouth for that matter. Sorted. We say: Pocket-sized, fuss-free filtration.
