Water bottle with filter

• This water bottle with filter puts the water through four filtration stages before it reaches you, instead of one membrane doing all the work.
• The cartridge lifts straight out and is replaceable, so the bottle outlives the filter you happen to be running.
• In 650 ml or 1000 ml, with the litre size for legs where the next water point is an hour of contour walking away.
• A latch holds the flip lid shut inside a rucksack lid, and the moulded carry loop hangs off a finger.
• For cold water only, so make tea in a metal mug and keep this one for drinking.

Water bottle with filter: four stages and a litre between refills

On a full day in the hills, legs regularly run further between water points than the kit list suggests, which is where the litre size earns its space in the pack. The bottle runs four filtration stages rather than leaving one membrane to carry everything, and the cartridge lifts straight out when it is spent, so you pull and swap the filter yourself and keep the bottle. The lid latches shut so it rides in a rucksack lid without opening, and the moulded loop hangs off a finger. Fill it cold and drink it cold. Blue or black, in 650 ml or 1000 ml.
