WHY ACTIVE suspension?

WHY ACTIVE suspension?

Black Diamond packs built with our award-winning active suspension systems—ergoACTIV, ergoACTIV XP, reACTIV and reACTIV XP—are unparalleled in comfort, efficiency and load transfer. Because the shoulder straps and hipbelt move with you, friction and hot spots are eliminated. The pack’s load stays perfectly balanced at all times—without adjustment—and allows your body to move naturally in any direction. This results in a more efficient, comfortable, longer stride—meaning you can cover more ground, more quickly.

Mission 55 Pack is rated 4.3 out of 5 by 10.
Rated 4 out of 5 by from Functional pack for the alpine I really like the features on this pack. The oversized floating lid, and the simple desighn is ideal. Also love the crampon pouch and tool attachments. My only complaint is the frame, although the suspension is very comfortable I don't understand why the frame has absolutely no lumbar support. It's completely flat. I feel like the fit and comfort would be improved if it was a bit more ergonomic for the back. I really like this pack and the shoulder straps and hipbelt are perfect, but I would have given it 5 starts if it had some shape against the back, instead of just a flat board. Great pack otherwise.

Rated 1 out of 5 by from Good Features, Horrible Durability I am a glacier and ice climbing guide and purchased this pack in January 2018 for my winter pursuits here in Southeast Alaska. It had all the features I was hoping for, reinforced crampon carrier, ice tool sheath, simple/streamlined construction. For my jaunts this winter it was a solid pack that did everything nicely. That all being said - once the summer guiding ramped up to a daily basis, and I started to put this pack to solid, consistant use, it failed miserably. I almost lost my mountaineering axe on a day trip because the velcro BD tool/axe holder completely disappeared on the trail - it just ripped off and slid off the end of my axe. Next, one of the straps on the shoulder strap ripped as well just by having the weight of a hand held marine radio attached to it. These small things are minimal compared to the fact that BOTH shoulder straps were ripping off from the pack itself with constant, daily use. By the end of it's life, I had carabiner'd and prussik'd the strap to the pack to keep it attached. Being an avid BD user and fan, I was very, very disappointed in the durability of this pack. I had recommended it to my friends and fellow guides this winter with all the features I mentioned above that I liked, but I have since rescinded my recommendations after the pack did not hold it's own on a daily basis this summer.

Rated 5 out of 5 by from Excellent Alpine Climbing Pack I recently purchased this on a slight discount after warranty decided that my previous Speed 55 pack was not reparable (or replaceable?) I was concerned about the weight, but found it to be light weight like the Speed 55. The shoulder suspension is truly the best I've found for climbing. Really like the side ziper to the main compartment and the ice tool attachment is finally bomb proof. Also the crampon pouch is a nice extra that I may never be-able to go without now.

Rated 4 out of 5 by from Excellent for ice climbing! I bought the Mission 50 (older model) two winters ago. Saw it in a store all decked out with rope and ice tools and crampons and that BD logo and that royal blue color, LOL, had to get me one! I haven't been disappointed, and will order the newer Mission 55 soon in hopes the 55 M/L is a little taller in the torso than my 50 M. (I'm 6'1, mostly in my legs, 195 lbs.) Outstanding features: Crampon pouch, tool pockets and straps, tuck-away rope strap, front AND rear haul straps (very handy!), comfortable suspension, roomy lid compartment that easily adjusts to low or high main compartment packing, easy open drawstrings, side (rope) straps. Fair: Difficult to bend my wrists enough to grab and tighten the shoulder straps (remedied with loops made out of 3mm cord), still trying to use the side zipper, and buckles are sometimes hard to squeeze and release (I'll work on grip exercises).

Rated 5 out of 5 by from Excellent mid-sized technical pack I was skeptical when i first bought it, i urgently needed a pack for a particular expedition in the states, but had left my packs at home in Australia. Being ex-military i was used to a different type of pack - my go-to was burly and 150L in capacity. But this pack has since got me through a solo 7 day trek out in the Yosemite wilderness and has replaced my pack for day-long technical ski touring trips. It has held up to fair bit of abuse, expect for a broken chest buckle (from overloading), which was a problem easily remedied.

Rated 5 out of 5 by from Best Alpine Approach Pack I've Owned! Perfect size bag to use as an alpine approach pack if you're going to be spending multiple days in the mountains. Incredibly comfortable, very functional and well worth the price. Just like the Creek 50, the side zip is invaluable on this pack. If you're in the market for a new bag look no further, this is it!

Rated 5 out of 5 by from Durable, Lightweight, Versatile, Comfortable I recently bought the Mission 55 Pack after already using the Mission 75 Pack. I simply wanted the same pack but smaller. In the picture below you will see me hiking Mt St. Helens with the Mission 75 Pack. The entire trek was comfortable and balance the weight evenly. The pack can withstand glacading even in icey patches. I enjoy the side zipper which allows easy access to a down jacket or a fleece without having to adjust your pack. The straps are small but fit well and are durable. I have also hiked recently with the Mission 55 in some of the hills in Korea. It is just as comfortable for backpacking as it is on an expedition. I definitely recommend this pack. Measurements: I am 6ft 200lbs and I purchased a Large. It fits perfectly.

Rated 4 out of 5 by from Good, Don't see the point in side zipper. Carries well, and packs nicely. I don't understand why there is an added side entry zipper, it just adds weight and a possible failure point to another wise good top loading pack. I do like that it has a crampon pouch.
