Input:
I bought this for day Hikes.  It was much cheaper then a Camel Back.  I Have gone on 3 hikes with it so far.  It holds plenty of water, and has lots of pockets.  I actually froze the bladder before the most reason hike and it still had an Ice block in it 8 hours later.  So it def keeps the water cool.  This backpack is perfect!
Oh and for the guy that said the water tasted funny the first couple times.  I ran Water through it 2xs before using it and its fine.  Pretty obvious fix.  I would have thought you would have rinsed the bladder out before using it anyway.
