Lightweight, efficient women-specific pack for your extended weekend treks.

When you plan an epic five-day trek along the Appalachian Trail or into Glacier National Park, haul your gear in the lightweight Arc'teryx Women's Altra 62 Backpack. Thanks to this pack's women-specific design, custom-fit GridLock shoulder straps, and rotating Load Transfer Disc, you won’t walk away with bruised shoulders or uncomfortable chafe marks on your sides or back.

  • 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

  • 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 for ventilation while you hike
  • Altra 62L 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

Returned the Pack

  • Gender:Female
  • Familiarity:I returned this product before using it

I'm inbetween sizes. The bar on the size chart overlaps both the regular and the regular tall sizes for my torso length. I couldn't get the pack to fit comfortably on my back fully loaded. I'm returning this pack for a Deuter that has a lot more adjustability in the torso and hipbelt.

I also noticed the materials on the hipbelt and shoulder straps are very scratchy and hard. The Deuter I tried felt more comfortable against my skin. Even with a collared hiking shirt to act as a barrier between my skin and the Arcteryx pack, the straps still were scratchy and uncomfortable.

Finally, I have a custom 12" bearikade because I hike for 5-7 days in the Sierras where bear cans are required. This pack was reviewed as holding more than the 62L on the label. I decided to give the pack a try based on these reviews. It really doesn't hold more than 62L. I couldn't comfortably squeeze the bearikade and all of my other gear into the pack. That was final deal breaker.

I returned this pack for a Deuter Aircontact 70+10 SL.

Unanswered Question

What are the dimensions of this pack?

Also could I ask for a bets guess opinion: I'm just over 5' tall and have a 15" torso, 125 lbs with a 30" waist. Do you think this pack would fit me?

I love the shape of this pack when compared to traditional cylindrical packs. It carries weight far more comfortably. This pack is so adjustable and customizable that I quickly came to appreciate how simple it was to dial in the fit and comfort.



Here's the pack with a few things unzipped and unclipped without anything in it - You can sort of see that the lid has two different cinch points and that there are a bunch of places to attach things to. The front zipper creates a kangaroo pouch behind it of sorts - and each side of the pouch has it's little pocket... then the zipper around the pack opens completely up (scroll down for more on that). The bottom unhooks to attach a pad, jacket, axe, etc. This means your stuff is protected if your pack is thrown down on the ground temporarily. Also you can see the daisy chain on the side of the wing-woman pockets.

Hip pockets - only downside

Hip pockets - only downside

They're a little small - an old school cell phone fits, a cliff bar fits, but not a ton of stuff - I don't mind this because I prefer to attach a sunglasses pouch here anyway which has a hard case protecting my essentials (phone, shades, etc) better than any hip belt pocket out there.

This pack opens up COMPLETELY meaning you don't need a sleeping bag pouch and you can get to anything in your pack - Like removing the top of a suitcase! It's AWESOME. You can also see here that on the sides of the pack there is a bit of daisy chain to attach stuff to.

lauren, thank you for this photo on how it opens up, I have been searching reviews to be able to find out more about the pack. I am currently torn between the Osprey Way point and the Altra. Seems the Altra may win this round.

Nalgene in Wing-woman Pockets

Nalgene in Wing-woman Pockets

I love these pockets - in some of my other packs things jiggle out of the side pockets - the zippers on these mean more safety and I can still get to everything - When I saw these pockets I wasn't convinced they'd work or be easy enough to open but I don't struggle with it (anymore than I did with the pouches) - it is also way easier to get stuff back into them than with the stretchy pockets in my opinion. Tons of room to easily fit lots of good stuff.

"external" bladder

"external" bladder

The bladder has its own pouch accessed by dual zips (so you can make where it exits tailored to you) - this means you don't have to shift through your stuff to get to your water - and unlike my osprey kestrel it doesn't push out into your back since it isn't "built" into the back

Super Adjustable

Super Adjustable

Lifting up the straps here - my measurements put me squarely in the overlap - I went with the cheaper one (smaller was on sale at the time for 200$ less) and didn't struggle to get it to fit because of these pegs - I like this better than many Velcro system straps because you're sure the fit is "even" on both shoulders.


AWESOME Pack - super adjustable & comfy

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

I tried on the Osprey Ariel 65 and debating buying it for months but held off and am glad I did - just before I bought it, I stumbled into this Arc'teryx Altra 62. Within a moment of throwing it on my back I KNEW it was the right pack for me. The fit was insanely good and the pivot belt rocked. It bears weight really well and the different interchangeable hipbelts (purchased separate) mean the hip belt is perfect - especially if you have wide-womanly hips.

The external zip water bladder pouch means you don't have to shift through all your gear to get to your water for re-filling on the go.

I love the way the chest straps adjust (individual slots vs sliding on most non Arc packs) - they don't slide up and down as you travel and stay put

The fit is perfect (at least for me). Being super adjustable - you really can toy and tinker with it until it's just right for you.


-Comfy and super adjustable so it's just right

-Spacious including extra space in the extension collar

- Great pockets (two in lid and front pockets also AWESOME)

-Shape - the fact that it's a very different shape means you don't have your head bouncing into firm uncomfortable pack backs like you do on most packs

-Wingman pockets mean your waterbottle wont fall out if you are bouncing around on the trail or if you bend over to tie your shoe - they really are accessible on the go too! (I was skeptical of this at first)

-Full zip opens pack wide so you can get to any or all of your gear - means finding stuff in your pack at camp is wicked easy

- Very well made (like most/all Arc products)


Hipbelt pocket is tiny - but for a few bucks you can pick up a pocket that you can attach on any pack (sunglass cases work well for this; soft but firm enough to protect stuff).

Price - I found it on sale for 220 which made it a steal for me. 450 would still have been worth it but steeper in price than most packs

No sleeping bag compartment - but the full zip opening is honestly better

Lauren, this is super helpful.

Thanks so much for sharing your experience.

I now have the confidence I needed to buy this pack!


I bought the Arc'teryx Altra 62 Backpack...

I bought the Arc'teryx Altra 62 Backpack - Women's - 3782-3965cu. Why is it so big atthe bottom compared to other backpacks? Should i pack the most heavy itenms at the bottom closest to my back/spine?

THere is a section on the Arcteryx website which tells you how to load your pack according to the terrain you will be travelling. I have posted the link (see the bottom of the page for reference
