Black Diamond Mercury 65 Reviews:

Positive Reviews:

I know, pretty broad statement, right? Well, that's what it felt like on a 8-day trip in the Pyrenees. At first, I was a little concerned if the 65 might hold all the backpacking (2P tent, sleeping bag and pad, clothing, rain gear, food), plus camera equipment (tripod, body, 4 lenses and accessories) for a week-long trip but the Mercury did awesome.
+ Back ventilation was superb, even in the 90 degree temperatures on the valley floors.
+ The ErgoActiv system worked as it is supposed to and exceeded my expectations. It moved really well with me on the narrow Pyrenean trails and scree sections, while always being supportive and feeling well designed, something I wouldn't say about another manufacturer other than BD.
+ Shoulder straps felt a little stiff at first but after a couple of miles, they wear in and you appreciate the support of the Swing Arm technology. Overall, the pack felt much lighter than it actually was (mid 40lbs. range I would guess) and I have to applaud Black Diamond (again) for designing a pack that allows you to hike more miles with seemingly less weight to carry.
+ The removable hip belt is gold when air travel is involved. You can board the plane knowing you can attach the hip belt once you picked up your pack, nothing gets ripped off. Easy call. The hex key stores away in the right pocket of the belt - perfect.
+ The hiking pole loops are cleverly designed and so are the additional straps that just store away in little pockets under the top lid and in the smaller front compartment, which is large enough to fit rain jacket and pants, maps, etc. at the same time for easy access.
Easily the best backpack I ever carried and I wouldn't hesitate recommending it.
Oh, and I got the Stone color, which is actually a little more on the olive-ish green side, yet, a color I would still classify as brown, just with said super light olive-ish color cast.

I bought this pack and so far I've been impressed. All the zippers are taped and everything is made well. I took it out on a 8.5 mile hike up Wildrose Peak in Death Valley. The pack road well and it was easy to adjust for comfort. Also, the pivoting hip belt and load adjusting cables move with you and feel natural. The side pockets are stretchy which allows you to put stuff in them even when the pack is full. Also, I liked how the pockets on the hip belt are easily accessible. I've had other packs where the pockets could not be reached very well. Finally just for some extra info the hip belt doesn't come attached. It is easy to attach but you may not realize the tool is in a pocket. I didn't realize that and I went and got an alan wrench from my garage when there was one with me the whole time.

Fantastic Pack

I purchased this pack unsure of its longevity - but it turns out it is a very durable pack. I would not use it if you are person who likes many pockets because it is essentially one big pocket. For me personally, that style works best. The pulley system that makes the pack stick to you works quite well (which is why I thought it might not be durable). After using it extensively for three months through the North Cascades and Olympics, I can say that it is a fantastic pack.

Great Pack

I have used this pack on overnight backpacking trips. I have no complaints! Great for storing everything you will need on an extended backpacking weekend. Lots of compartments for good organization, and easy to access on the trail. Overall great Pack!

Great bag if the zipper closed

I use this for hiking, bought it last year and the zipper on top has broke already after only about 5-6 day hikes.. Other then that the pack is great, hopefully they'll read this and attempt to rectify the problem...
