Description

For multi-day trips or light-packing weeklong hauls into the backcountry.

Save energy and keep your trek into the backcountry light with the Arc'teryx Men's Altra 65 Backpack. Ideal for multi-day or weeklong backpacking adventures, the Altra expands and compresses to the size you need while also providing the comfort, support, and stability you require when you're slogging up a scree-covered rock field or a steep trail to high-mountain lakes.

  • C² (composite construction) system's minimized construction lamination decreases pack weight and makes the pack sit close to the body, which minimizes load movement and backward pull and increases energy conservation
  • Load Transfer Disc naturally moves with your body while distributing the pack's load weight to your hips for improved comfort
  • GridLock shoulder straps adjust for both height and width
  • Ergonomically shaped shoulder straps feature 500D nylon with silicone-treated PU fabric for durability and protection, a Hypercell foam for stability and comfort, and SpacerMesh lining for airflow
  • Twin 6005 T-6 extruded aluminum M-bar stays are rigid and lightweight to provide structural support
  • 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

Unanswered Question

Your site lists the Diablo Red in Short and Short/Regular. What's the difference? Does the Short come with a small hipbelt? Thanks!

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

We have some on order from Arcteryx right now. Unfortunately, we do not have an exact date as to when they will be coming in, but it should be sometime at the end of the month. Hope this helps.

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!

I must agree it seems they are making packs not for over 60 pounds. Arc'teryx & Osprey among others.

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

Best Answer Responded on

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!

Responded on

Davis is spot on.

Here's a link to the "Contact Us" form:

http://www.arcteryx.com/Service-Forms.aspx?EN

You can contact them and ask for a free sample of the lube.

Anyone know if just white lithium grease would work?
Or would this be an issue with the plastic?

Responded on

Never tried it, but I would probably opt for silicone grease over white lithium grease which is intended for metal/metal joints and could potentially dissolve plastics depending on the solvents used.

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 Responded on

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.

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!

Glad I purchased this pack!

  • Familiarity: I've put it through the wringer

I spent a lot of time researching about getting a new pack. I know arcteryx gear is great but not a lot reviews out there. The wife and I were heading away on a life journey. 14 months away from home. I needed a pack that was durable, but also multi purpose. Great for hiking but also for travel.
I am so glad I settled on the altra pack. One for the wife, a 62, and a 65 for me.
It's an incredibly well thought out pack. So many places to store stuff. Very comfortable with the waist belt design. Yes it might sqeak. But as long as you lube the swivel belt occasionally, no problems.
So far we are 6 weeks into the trip. But so glad we got these packs.
Sorry backcountry. I bought them somewhere else. But wanted to share the info for interested people.
