    • Back panel consists of HD 80 foam for support and structure, burly double-weave fabric offers strength and durability, and the back panel sits away from your back to boost ventilation
    • Altra 65L is available in regular and tall and works as a fast-and-light pack for multi-day trips in the backcountry
    • U-shaped zipper offers easy access to your gear
    • Extendable top lid and extension collar enable you to carry larger loads

    What do you think about this product?

    Have questions about this product?

    So, so many pockets

    • Familiarity:I've used it once or twice and have initial impressions

    I have only used this pack a few times. But it has surpassed all of my expectations. It fits my body perfectly, and has pockets everywhere I would want them to be. It makes storage a breeze, and feels good on my back.

    Great backpack at an expensive price

    • Familiarity:I've used it once or twice and have initial impressions

    The pack is great.

    Tons of adjustments that make the pack fitting you perfectly, while you wont find them cumbersome when not in use.

    Pocket designs are good as well, love the kangaroo pocket that allow quick access of things like gloves and coat; wingman pocket for easy access of water bottle; and the main compartment could be fully opened for easy access.

    The pivot hip belt does help, but also does make some sound, but the sound become minimal in a trip or two, and that's not a problem to me. I also love that the belt could be removed and be be placed around the pack, this makes sending the pack as a baggage in the airport a lot easier!

    All in all, it's a great pack that is comfortable to carry and easy to access. But it is also way more expensive than it's competitor. If you want a great pack and don't care much about the price, this is the one to get. But if you are looking for something of great value, I'm sure you could find another pack with most similar features but at a much lower price.

    Great pack, check sizing options.

    • Familiarity:I returned this product before using it

    This pack is simply amazing. It has many adjustable features allowing you to tailor the fit perfectly. However, do be aware of the hip belt sizing options. I ordered the short/regular pack and received a small sized hip belt. Backcountry.com is unable to exchange the belt and will require you to deal with artery'x directly.

    Best pack ever!!??

    • Familiarity:I've used it several times

    I'm 5'6 150 and ordered a small reg. The fit was spot on. The rotating hip belt is what makes this pack great and the padding wasn't overly hard but very comfortable. I walk with my hips. When you walk with this pack the hip belt moves with your hips and the pack stays put to your back. No swaying back and forth. I didn't feel like I was going to tip over while doing some light scrambling or when going up steep inclines. Several reviews people have complained about squeaking from the shoulder harness to the hip belt. I added a decent amount of synthetic grease and no more squeaking. Even when there was a slight noise coming from the pack it still doesn't change how comfortable the pack is. There is tons of space and the wing pockets make it easy to fit my Nalgene bottle as well as other decent size items. My platypus big zip 3L fit in the main water compartment. The Altra 65 price is really steep compared to other brands but I love Arcteryx and def recommend this pack. Don't let the price fool you, it's worth it????

    Best corporate pack

    • Familiarity:I've put it through the wringer

    What a great backpack. The price is a bit much, but once you get your hands on the bag and especially when you load it up I can see the difference. I got this pack to carry my stuff more comfortably and to also haul a few things for others as well. The ergonomics of the pack are amazing. Just lifting the pack from the handle (never the harness!) is ergonomically better than I've seen. It goes on without the shoulder straps all twisted and jumbled. Also, all the straps are handy to reach and the pack is very adjustable. I really think the lid is amazing. So simple yet such an improvement. The workmanship, materials and layout of this pack are just wonderful. I cannot access the zippered wingman pockets with the pack on, but that doesn't matter to me for I use a hydration bladder. The pockets are great though. The hydration pocket is large enough to accommodate my 3 liter bladder and a flat style 750ml bottle of whatever. I really love that I can have this pack quite overloaded, but I don't look like the the Beverly Hillbillies. Everything gets into the pack and is concealed. The compression straps are EXTREMELY effective as well. Some designs improvements for me would be: ditch the zipper as I have only used it to see if it is practical and it's not for me, the draw cord on the "snow collar" isn't sewn in at the top so when I'm overloaded I have to manually move the draw cord up to the top of the collar before cinching it down. That's about it really. I am sending the pack back because over 65lbs and it starts getting pretty uncomfortable. It's a bit surprising to me for I have no problem getting that kind of wt into the 65 yet the suspension is the same for the 65-85. So, I must go with another pack (Kifaru) that is meant to carry heavy loads better. Even the rep at Kifaru almost had me sold on the Altra. If I could only get my weight down it would be great! If you stay under 55 lbs the pack is wonderful. Over that and you may want to look elsewhere. Great pack!

    First Arcteryx pack

    • Familiarity:I've used it once or twice and have initial impressions

    Okay so first off, I cannot say anything about how this holds up over time because I have not yet had the chance to get out for a long hike with it. I will just comment on the build and general features for now and will follow up with comments after using it over a few days time.



    Color: Like David Thiel mentions, the color is not the copper look in the picture, but it is more of a brick red. Now I hate red personally but I really actually like the look on this. The build quality seems to be extremely good. I don't see any areas where any stitching is loose or even any uncut strings or so forth like I find with a lot of other products. I guess one would pretty much expect excellent quality given the price though.



    Features I personally love: The large external zippered compartment on the center of the back is absolutely awesome! It is large enough to accommodate a variety of items. I tried my tent poles, camera tripod, rain jacket and a few other things and find it makes a really great universal stow-away pocket to keep odd sized items out of the way. The two side pockets are really big as well. The right amount of room where you can easily insert a 32oz. bottle without fighting with the pack. However, I will say that the accessibility (at least for me) is not really all that easy to reach around and easily get to. Not a huge deal really, but I think if the side pockets were gapped a few inches more towards the front and they would be really easy to access. Some people might have a longer reach obviously, so might not affect everyone. I did find one of the side pockets is a great area to put my headlamp and fire kit. My Jetboil Flash also fits nicely inside as well as a GSI Halulite Microdualist kit.



    I think another fabulous feature is the double-zippered compartments on the top of the pack. Just that extra bit of foresight that Arc'teryx had to recognize the need for organization in a pack is nice. The padding and unique swivel hip connection is crazy cool and comfortable. This pack made me a fan!

    Is it at least water resistant? I read the description and am not entirely sure what "water pickup" means. If not, would it be a bad idea to add a water proofer? Spray or wash?

    Where is the Altra 65 Backpack manufactured?

    when will the red model be available in a reg/tall?

    What kind of grease are you supposed to use for the load transfer disc? Mine didn't come with any grease.

    Best Answer

    Here's what Arc' says:



    "

    Special AC2 lubricant may be obtained from most Arc'teryx retailers. If AC2 lubricant is not available, contact our Warranty Department



    Alternately, you can use plumber's silicone grease as a back-up, available at most hardware stores or scuba dive shops.



    Do not use oil based lubricants such as WD40, as it will cause the Discs to seize and degrade the urethane components."



    ... and I hope that helps!



    I would just call them and they will send you a little tube of lube!

    If my back length is 19.5", would it be better to go with the short/reg or the reg/tall? The size chart has the short going up to 20" and the Tall starting at 19". Is it just a coin flip, or would there be a benefit to being on one end or the other end of the scale?

    Best Answer

    Dave,



    The deciding factor for me would be the desired pack capacity, because you could go with either since you're right on the cusp- the Regular is 3965 - 4453 cu in, while the Tall is 4148 - 4575 cu in-- do you want/need the extra 183 cubic inches?



    Feel free to give me a call if you need anything else- I can be reached at 1-800-409-4502 ext 4456, or llabar@backcountry.com.

    Can someone give me the approximate dimension...

    Can someone give me the approximate dimension of the pack moderately full? Just curious how much larger it is, since I've never used anything bigger than a 45L. Thanks

    Here you go. These are approximate but give you an idea. Had this pack to normal capacity (65 liters) ... with the kangaroo pocket packed with rain gear. The pack was not completely turgid, but full.



    When viewing the back with the hip belt facing away from me:



    33 inches high

    14 inches wide across the main body

    19 inches wide across the wingmen

    14 inches deep



    I hope that helps.



    My guess is this thing will stretch up to 1.5 inches in each of those dimensions... except height, where it could rise like another 6-8 inches if needed.



    This pack is GREAT. Hope you buy and enjoy it. It's crazy expensive, but it's cheaper than a Ferrari or an extra-marital affair!

    Happy to help. You got lucky: I was doing a gear demo to some new boy scouts today.



    I find it's a very versatile pack. I use mine for 2 mile "expeditions" with 10 year olds, then turn around and use it for 15 mile-per-day through hikes with my friends on the AT.



    Love this pack. It WILL squeak on you, so do carry the grease if that sort of thing drives you nuts... but that's it's only fault. Other than that I honestly can't imagine anything better and I've used a lot of packs in my life.

    with the arcteryx altra 65, since it's not waterproof an i'm new to camping is their a means to waterproof the pack?

    Gary,

    While the Arc'teryx Altra 65 Backpack is not waterproof it will be very water resistant and should shield the contents of you bag from moisture in most circumstances. However, when the precipitation is really coming down you will want a pack rain cover. Most packs don't come with them but Gregory makes a good durable model:

    Best Answer

    It's often more effective to waterproof what's inside the pack by means of ziploc bags, etc.



    Stil.... Arc'teryx makes a pack cover specifically for this pack. It's a little heavy and it's a little expensive, but it fits perfectly and will keep everything dry.

    Can you attach ice axes to the pack? I see in the video they use the smaller version of this pack with ice axes, is it possible?

    Best Answer

    Hey,



    Yes, the big expedition sized Altra packs all use basically that same P'ax system that you saw in the videos. For carrying, you would use both loops at the ends of side compression straps, but for one-hand, what you do is slide the axe or ice tool shaft under just the upper loop, lift a little, then slide the axe head into the sleeve you see the lower comp strap going into at the bottom of the pack. I know it might sound confusing, but it does work. Watch the videos again and scrutinize the Altra's features, you'll see pretty much how it works.

    How many liters or cubic inches is the main compartment? (not the Kangaroo pouch)

    Best Answer

    Arc'teryx equipment team: "The capacity of the entire pack is 65L when the lid is closed at its optimal height. This closure can expand to overstuff the pack and the capacity goes up to 75L's total. This however may leave some spots on the pack susceptible to water leaking in and hitting fabric that is not as water resistant.



    The Kangaroo Pouch has a capacity of approximately 12L So the (main compartment) Pack will be 53L with an expansion to 63L total."
