Mountain Hardwear Fluid 48 Backpack - 2900cu in

I would have to say the only thing I didn't like was the hip belt pockets, they are way to small.

I hike with that backpack through Carpatian Mts. in a 5 day trip (about 60 km). I took S\M size (my torso lenght ~50 cm.) The pack sits perfectly on my back. It has many useful adjustments.
There's two side pockets which you can use without taking off the pack from shoulders.
Inner space separated on two volume by valve. In a bottom part you could easily store sleeping bag and tent. In a upper part placed pocket for 3L CamelBak (zip of this pocket stored outside the pack any you can easily use it whenever you need).
You could remove the top pocket, it useful for one day trip (Backpack perfectly shrinks by straps). But when top pocket is removed from in a backpack is not enough small pockets for various little things.
You could easily hang tent or sleeping pad on a special bottom straps, placed outside of the pack.
Unfortunatelly the pack sells without rain cover (sells separately Mountain Hardwear Pack Rain Cover - M). I bought M size rain-cover, but I think it quiet big (however, I didn't fill a pack in full).
It's great lightweight backpack for this money!

I really did like this pack. Great features and super light. HOWEVER, I took it on one trip - ONE trip - to Capitol Reef, UT and one of the side panels ripped while doing some tough scrambling through sandstone. I figured "This pack shouldn't have failed after one trip! Mountain Hardwear will surely stand by their gear." So I sent it in....

I get a call, and the guy tells me that they won't replace it or repair it. They tell me that their pack can't stand up that use. AFTER ONE TRIP. So sad to get this kind of reaction from what I though was a quality , hardcore outdoor company. Stay away from their packs.

I took for a 3 day trip through the Grand Canyon (28 miles) and I like the pack very much. I can't think of one complaint. Plenty of compartments so you can keep the necessary things at a quick grab. There's two side water pouches that I fitted with 32oz bottle of water with for easy access. I could easily grab them while walking and put them back without help or stopping, a huge plus on any trip. I fitted the outside straps to strap a 3 person tent. It was very comfortable after I got used to all the straps. For the size of the pack there is nothing to complain about it does everything you payed for and more.
