Black Diamond - Mercury 65

Built for rough trails, big-mileage days and maximum comfort over the long haul, the Black Diamond Mercury 65 Backpack combines classic backpacking features with sleek, modern designs and unparalleled freedom of movement. From a long weekend on the John Muir Trail to a lightweight week in Canyonlands, our ergoACTIV XP suspension system uses a custom, 3D pivoting hipbelt with urethane tendons, a men's-specific fit and SwingArmTM shoulder straps for increased stability and dynamic load transfer. The pack's front zippered panel gives you full access to the inside, while multiple pockets, dividers and straps help secure and organize your gear during extended trips.

SwingArm Shoulder Straps: These shoulder straps move in concert with a hiker's stride or a climber's reach by sliding through the bottom of the pack with low-friction cable and housing. Each strap is linked to the other by the cable, which maintains an even, balanced load across both shoulders.

ergoACTIV Hipbelt: The key to the ergoACTIV suspension is a proprietary, custom-shaped ball joint that attaches the hipbelt to the frame. This simple, durable three-dimensional system allows the hipbelt, and by extension the backpacker, hiker or climber, to move unrestricted in any direction. Gender-specific cant and shape provide optimal comfort on select models.

M-Motion™ Frame: The 6 mm 6061 aluminum frame in ergoACTIV XP packs enhances stiffness and load transfer, and has a 20 mm center stay for added support and backpanel contouring.

Product Reviews

not well thought out
This pack is a real let down coming from a company like BD. The waist band is so thin and the padding is sparse that it makes it uncomfortable. The shoulder straps are thin and also have very little padding and dig into my shoulders. There is a surprising lack of pockets on this pack. The front of the pack has one zip pocket, with one small zip pocket inside. The zippers have great waterproof tape on them, but where the zippers meet there is a hole that lets water in to the pack.
You have to assemble the waist belt after you purchase the pack. This is a cruel joke on consumers! Trying to get the allen wrench into the slot is a real trick, and then the screw will not engage into the hole to secure the waist belt. The 'rocking" waist belt is also not the best idea that I have seen. The buckle on the waist band is really small and fragile and I don't expect it to last very long.
The pack is also lacking in tie downs and places to attach equipment,
I do not recommend purchasing this pack. Review by explorer
