I was down at the outfitter today and I like the katadyn pro hiker water filter.

I tried only using aqua mirra on my last weekend trip, but I was constantly low on water. I like being able to drink from the water source right away so I can carry less water.

It has a feature that will allow it to connect to a hydration pack and pump the water straight into your pack! This is super cool, however, which hydration packs does it fit?

Does it fit a platypus?

I have an osprey kestrel pack which is hydration compatible.

Will a katadyn prohiker filter and 2L platapus work well with my pack? Does anyone have any experience to share?
