Pivoting Hipbelt Great For Lower Back

I was searching for the lightest pack I could find that could still handle a decent load. After extensive research-and a couple of returns-I found it in the Altra 65! An almost perfect pack. Having given the Altra 65 a couple of short wilderness excursions, including my most recent 25 mile trip, carrying about 39 lbs. to Yosemite's 10 Lakes Basin, I think I can give a fair assessment of this packs pros and cons. First off the "squeaking" shoulder strap that some people complain about, which was pretty persistent the first 5 miles of my trip. After stopping for lunch and then refitting the straps, I noticed a significant decrease in this somewhat annoying noise. The noise didn't really bother me-even at its worse-since I knew it wasn't just MY pack and others had experienced the same issue. The next day I hiked another 9 miles and hardly heard this sound again. I really think this is just part of the breaking in period for the pack with the rubber slots needing to wear a bit. Even if this problem persisted it wouldn't be enough for me to give up such a wonderful lightweight multi-purpose backpack! I really like the highly personalized fitting of the shoulder straps by way of a grid of various slots-which made it possible to get exactly the right fit for my shoulder width. This is something that can be tweaked with hardly any effort as one's load changes. Another perk is the extra-wide water bottle slot, which is perfect if you need to carry a Bear Canister (required in Yosemite) With my old Bora 80-or any pack for that matter-it is almost impossible to squeeze in with a full water bottle. with the extra-wide pouch I simple slid the CamelBak over to one side and the bear canister the the other. This makes sense from a weight distribution standpoint as well. I really appreciated the heavy-duty zippers on this pack (something I didn't find in any competitors). While the body uses a much lighter 220D Ripstop than it's heftier cousins, it is significantly more durable than any other popular pack on the market. This is not a cheap pack-and it is not made like one. First quality all the way. I found the side pockets to be deceivingly roomier than they appear, easily carrying a large fuel bottle, extra water bottle, fishing poles, fly reel, tackle and trekking poles. The micro daisy chain is handy to have and while the straps are much smaller than your standard issue backpack, they are ample for handling the load. I had this pack full and what I would say is weight capacity of 40 lbs, but it felt like a dream-virtually floating on my hips. I especially like the pivoting hip belt, which takes even the slightest hip movement off one's lower back. The easily detachable feature came in handy when loading for travel. Great lighter weight pack without giving up creature comforts. No unnecessary bells and whistles.

So far it's the best pack I've ever owned. Really comfortable, and it is one of the best made ever. At just barely five pounds it's pretty light for what it is.
I'm sure most folks know about the features offered in this pack, so rather than listing them, I'll offer an opinion on some of the more discussed aspects of this packs design. At just under half a grand, this is one of the more expensive packs on the market. Unless you're thinking of a custom job, this is about as pricey as the high quality backpacks come. In my opinion, it's worth every penny. Time will tell (I've had mine for about a week) obviously, but from everything ranging from weekend trips to hard core thru-hiking, this pack will deliver for years under hard conditions. The craftsmanship is outstanding. Comfort and solid construction are what really appeal most to me when looking at packs and this thing is built from BOMBER nylon, with really tight seams, nice zippers, and strong adjustment straps. All stitching is impeccable. It's not completely waterproof by any official standard, which seems to be a big topic with this pack, but I would never expect any pack to be. Buy a raincover (which you should get with any pack that will see any real use) and you'll be fine. A+ for build quality is what I'm saying here. It does beat out packs by Gregory and Osprey in this category, in that it's slightly better assembled, more usable, and lighter (lighter than the Gregory packs of the similar size, at least)
The biggest con that I heard about this pack was regarding its (ingenious) attachments for the shoulder straps and the load transfer disc in the waistbelt of the pack. I have not had this thing squeak on me yet, which supposedly is a huge problem, in both the waist belt and the shoulders. I would go for it if you're passionate about laying hands on one. This 2013 model really seems to have hashed out the older problems with the previous model. Again, this pack rules the land of backpacking.

The 2013 Altra is a huge improvement on the original. They've kept everything that was great (suspension, hip belt, U zipper, etc.) and fixed all the design flaws of the original. And then the piled in some extra goodness.
Key differences and improvements:
-- H2O bladder is now accessible from outside the pack, and it's centered.
-- Brain of the pack (which now only has two pockets) is removable.
-- Brain of the pack is designed to sit on top of the pack a little more reliably.
A couple additional details: the H2O bladder is a separate pocket that hangs down inside the pack and velcros to the frame sheet. Makes it easy to turn it inside out out and help the pack dry.
As for waterproofing? This pack is not waterproof and in any meaningful rainstorm it will soak through rather fast. On the plus side, it dries out quick.
Most of all, I love the "Wingman" pockets. I have these style pockets on my MTB backpack (an Ergon BC2) and love them. Here on the Altra they are easy to access--and HUGE. They are large enough to put a 1L nalgene bottle in (with ease), but what I had hoped for has come to pass: I can keep my DSLR with a superzoom in one of the wingman pockets and access it quickly, without taking off the pack. AWESOME.
Oh.. and they got rid of the compression wings, which were kinda silly.
One last thing: the Iron Oxide picture they show is ENTIRELY INCORRECT when it comes to the actual color of the pack. (It seems the picture above is based on the "Copper" color of the previous model). The actual color of the pack is almost a brick red, with copper-orange straps. I was surprised when I pulled it out of the box, but I like the actual color much better. I've attached a photo.

Fine Backpack, but could be better

The pack got here quickly, and REI worked hard to get it to me in time for a major trip. I loved everything I saw in the pack, and really enjoyed carrying it the first day. But the second day, one shoulder strap began to squeak, then the hip belt developed a small squeak. I wasn't too worried about the hip belt squeak, because a tube of lithium grease is provided for the rotating joint that holds the pack to the hip belt, and when I removed the hip belt and redistributed the grease it would quiet down. But the shoulder strap squeak was very loud and there was nothing I could do to get it to stop. The shoulder straps are held on by ingenious lug and t-slot joints and adjust easily, but the plastic to plastic joint would not stop squeaking. I reluctantly returned the pack to the store for a refund. If Arcteryx could get rid of the squeaks I would purchase another in a heart beat! Except for the noise it's the best pack I have every carried for comfort.

Simply Awesome

I haven't had it for long, but so far I'm in love with the Altra 65. The build quality is far above the TNF pack I was upgrading from.

Once I got the pack adjusted correctly for me, it was super comfortable, and the rotating hip belt is definitely a nice addition. It sounded like it might be a gimmick, but it really does help me forget what I'm hauling around.

I look forward to many adventures with this pack.

Great Quality BUT Squeaky

I'am fairly new to backpacking. I brought the small size, I'am 5'7" and 165 lbs. I had to bring it back to REI . After hiking for about 15 minutes the disc on the waist belt began to squeak, which became annoying while walking. I checked to see if the grease thats supposed to be on the disc was there and it was. It seems that Arc'teryx can not get this right, it's been an issue for a while now. I was very disappointed I had to bring it back because I thought that this was a great pack otherwise. The reason I gave it 3 stars was because I think while in the woods you should not have to listen to loud squeaking but to the sounds of nature around you.

Wonderfully Comfortable Pack, but Noisy

I planned on using this pack to carry slightly heavier loads during the winter seasons. I loved the pack in every way, but once on the trail it began squeaking loudly in the right shoulder strap. The ingenious lug method of attachment of the shoulder straps also caused a persistent and loud squeak where the lugs attached. Arcteryx even included some lithium grease with the pack, but that was mainly for the rotating hip belt load bearing system, but the shoulder strap was the worse. I could not get it to be quiet so I returned the pack immediately. I would have given this pack a perfect 5 if it hadn't squeaked.
