Negative Reviews:

I had such incredible high hopes for this pack. But it appears that in a rare misstep, the arcteryx folks have lost the plot on packs in this size range.
The pack itself is clean, well thought out and lightweight. The suspension, if you can even call it that, is a joke. The hipbelt doesn't even deserve the name, it is so incredibly thin and flimsy. Zero weight transfer. I know arcteryx is all about elite atheletes who apparently like pain and carrying 58 Liters of gear (full expanded size of this pack in a Tall) all on their shoulders, but that kind of elitism is getting a bit rampant up at arc HQ.
From the company who once understood that competent suspensions are part of 50-55L packs, this is a dismal failure. The new Gregory Contour 50, the Deuter 50 ACT, those are packs that can comfortably carry 35, 40, even 45 pounds ON YOUR HIPS. You know.. where the weight should be.
This pack... gets returned. I give it two stars because aside from the laughable suspension, the pack design is quite good.

Poor suspension overshadows all else

All I can say is, I completely agree with Mistervee's review. I can tell he is on the same odyssey I was once upon: the perfect pack in the 50-60L range.

The Altra 50 pack design is superb. The suspension is indeed "inadequate, wimpy, almost non-existent." I have tried to understand who this pack is made for... backpackers who carry 50-55L of foam? 55L of gear generally has some weight to it, and you'd think a company as heralded as Arcteryx would have given this pack a suspension to reflect that.

Mine also got returned. And also to Mistervee's point, where's the photo of the suspension? Arcteryx also conveniently leaves it off their own website on this particular pack. Almost as if they're ashamed.

Neutral Reviews:

Pack design great, but the suspension...

The design of the pack is based on the Altra 65, and it's a great pack design. The suspension system however is based more on that of a book bag or daypack. I was looking at this pack for long distance hikes and possible use on the AT, but the suspension is not comfortable enough for day-in, day-out use. I don't think it would be even good for a weekend trip unless you were carrying 15 lbs. or less. I thought this pack had a similar type of pivoting hip belt and comfortable shoulder strap suspension as on the Altra 65, but it DOES NOT. (REI take note: how about showing a photo of the suspension system like you do for so many other packs?)

The hip belt is somehow fused to the pack body, is immovable, and the hip belt padding is inadequate at best, wimpy, almost non-existent. The length of the padding on the belt barely wraps over the hip crests at all. The same type of thin foam is used on the shoulder straps also.

Considering this is part of the award winning Altra pack series, and it has a 50 liter capacity, I was expecting a suspension system that could carry at least 25± pounds...maybe even 30. The pack itself could hold this much stuff easily; the pack body, hood, and other components are rarin' to go. If only the suspension could keep up.

With a better suspension system and with the option of adding a little more volume with the top sleeve (I'm thinking resupply here), I would have kept this for sure, even if it weighed a few extra ounces. I'm looking for a light but comfortable carry. As it is however, I'm returning this and looking for another pack in the 50-60 liter range.
