    Rugged, ready to go. When you don't need to carry a lot on a hike, this is what you need. Room for wallet, keys, so your pockets are empty.

    Best water source

    Posted by Anthony on Jun 6th 2016

    The Camelbak is the best product on the market for a water source. I use this product all the time and have never had any issues. It holds up well under constant use.

    The Best

    When the Army issued this to me they gave me a cleaning kit with it and it was a life saver. These have always been the best in hydration.

    Used this product during CAST training...easy to fill and use!! Kept water cool and straps were long enough to fit comfortably over battle rattle. Great product!

    Helped Win the War!

    I got issued this at CST, from Ft Dix. This sucker was a life saver. I had it clipped to my IOTV, and it went everywhere with me. I would usually just put water in it, but occasionally I would get CRAZY and put some MRE fruit punch in there. I was able to wash it out really easily with the Camelbak cleaning kit. I found it very easy to fill, too.

    I love my camelbak. There is absolutely nothing bad I can even think to say about it. It's comfortable, easy to use and keeps me alive on long hikes. Good things all around.

    Works great

    I use this little guy everytime I just need fluid... A lot of times I have to switch it out for a bag with pouches, but it's a life saverwhen all I need is water. Never leaks and jumped with it more then 10 times and still hasn't burst on the dropzone. Great buy!
