Comforting - General Ecology XL Water Purifier

It is comforting to know I will not have to worry about unsafe water.
Purchased this for an Appalacian Trail hike I am planning. Water comes out crystal clear.
Not as small as a Steri-Pen but it filters out everything you don't want.
Comes with Gravity/Storage bag.
