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 4.6 out of 5 by 12.
Rated 4 out of 5 by from Well Built Overall very happy with this backpack. Distributed weight really well. Material is durable. The only thing I would change on this pack, is I think it should have daisy chains on the bottom of the pack for tent storage, sleeping pad, or sleeping bag.

Rated 3 out of 5 by from Difficult to size I've owned a few mission packs now. I love the pack for the climbing specific features and weight/durability combo. It's light, but can handle some tough use in the mountains. However, my last mission 75 was a large, and I had to adjust the hip belt basically to the end in order to fit my small waist. This causes mobility issues because the hip belt comes all the way around my hips to about my belly button in order to cinch it down and it restricts my hip flexors. This time, I ordered a small/medium thinking it would fit my hips better, and it does! But now the back is too short and I can't get the weight onto my hips without causing misplaced shoulder straps that ride up to high. I guess the lesson is that I need a small hip belt, but large pack. Bummer. I am 5'11'' and about 140lbs depending on the day.

Rated 5 out of 5 by from Great pack with so many features that are right on Bought this pack for a week long trip of climbing in the Windrivers. Perfect for mountaineering. The crampon pouch is awesome. Side zipper that allows quick access to gear is brilliant. Quite comfortable for how light it is.

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 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 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!
