My betterhalf got this for me on Ebay. It was to big for anything I wanted at the time. But now, I love the darn thing. Amazon.com : Camelbak Motherlode 100 oz/3.1 Army Universal Camo : Hiking Hydration Packs : Sports & Outdoors It has just enough pockets inside it to make it easy to sort items so you can find them when you want them, without going hog wild. It is tough. I have been abusing Camelbak gear for years. And honestly have never worn anything out. I have given it away to friends and got myself new stuff, cause I wanted to try something else. But never had anything that I have considered unusable. They do produce one heck of a strong product. Guess that is why the military uses them too. It is comfortable. With my Tacticaltailor Combat Harness and this pack on, I am able to hike very comfortably. The belt helps to move the weight of the pack to your hips and not on your shoulders. The shoulder straps do spread the weight comfortably across your shoulders. The sternum straps help to keep the shoulder straps from falling off your shoulders and/or being pulled off in when moving quickly thru heavy brush. The bladder makes it easy to haul water, and like all Camelbaks. The bladder also works as a cushion against your back when totally filled. The mouth pieces of the Camelbaks work much better than any other I have tried. It is simple, yet it works. I would recommend this a great multi-day pack that you can count on. As mentioned above. Watch for them on E-Bay. My betterhalf got mine for around $60 with tags still hanging on it.
