I use a hydration bladder which I've added an inline filter to.

My biggest reason is so that I don't have to stop and wait on the refill. The Sawyer filter I use is good for life and is meant to be used inline. I can also gravity filter for others at about 1 liter for 1:20 seconds. All in it's 7 oz for the filter and hydration pack together.

Here's a pic:DIY inline filter in a hydration pack.
