Katadyn Pocket

Expensive? yes. Heavy? yes. Do I use it often? Not really. Nowadays for most water filtration I've ben using Katadyn Befree, because is so much more practical and easy and weighs nothing. But the Katadyn pocket is always on my backpack because it is the only filter you can rely on when everything else fails. Other plastic filters break or malfunction when you need them most, Katadyn Befree can get clogged or punctured, but the katadyn pocket is a workhorse and is always ready for action...I often do multi-day trekking with kids or alone and in those situations I need to make sure I can get enough clear water out of the dirtiest stream or pool. The katadyn pocket is the only filter I can rely on for that. Water is your nº 1 need while trekking in good weather. Without water trekking quickly moves from joy into hell and so being able to get cristal clear water every single time is well worth the extra money and extra weight. This filter is awesome!
