Solid pack with some frustrating design choices
Jeff2 years ago
I was excited for the release of this pack so I bought it on release and used it on two overnight trips. Previously I was using a Gossamer Gear Mariposa on my Pacific Crest Trail hike, and an Osprey Exos (the version without hipbelt pockets) before that.
If you want an ultralight pack with a vented back panel this is your ticket - it's more durable and dependable to any of the Z-Packs Arc series. However, it comes with some mediocre design choices. I've never been a fan of Osprey's side pockets, they're usable, but not that easy to use. Grabbing a water bottle is much more difficult while hiking compared to the Mariposa, so much so that I found myself drinking less water.
The ventilated back panel is great, but making the shoulder harness adjustable comes with some drawbacks. I do not think the toggle that goes into the plastic ladder on the back panel is a good design choice, it's quite easy for the toggle to pop out entirely while picking up or moving the pack, meaning you'll have to set it back in position. Additionally, since this system is not securely in place, the pack is quite bouncy. I was able to reduce this by lowering the shoulder harness another notch, but it didn't elimate it. When you are hiking downhill, especially if coming off a multiple foot drop on rough terrain, the pack will bounce after hitting the ground and feel momentarily lighter, then come down with more force. It's not a huge problem, but it's definitely a bit disorienting. Especially if I'm coming off a large drop, I don't want my backpack shifting around on me. The previous version of the Exos that I had had some slight bounce, but the Mariposa does not have this issue.
Also, you need to check if your plastic ladders are level if you buy this pack. Mine were off by half an inch, which is ultimately why I returned my pack. It may have caused some of my bouncing issue since one shoulder strap would be differently tensioned than the other, but I think the bouncing is inherent to the design. This discrepancy caused a bit of shoulder pain on one side due to the load not being evenly dispersed.
Another quality issue I had was a missing hipbelt buckle, the pack I recieved only had the receiver buckle and webbing on one side. Thankfully I had an old Osprey Talon backpack that had the same style buckle and webbing, which held me over until Osprey sent me a new buckle, which was pretty quick to their credit.
The stretch back pocket is a good design, but for some reason Osprey decided to attach the side compression straps to the top of the pocket. This means you have to choose between a having the compression straps tight, and an easy to use stretch pocket. I've never had issues with things falling out of a stretch pocket, I'm not sure why they went with that design. Also, the stretch fabric at the very top of the pocket was already pilling after 40 miles so I have durability concerns on that.
Lastly, a design choice inherent to almost all Osprey packs, this backpack is tall and skinny. It's not hard to get used to but it makes going under fallen trees much more difficult. Especially after using a shorter and wider backpack like the Mariposa, the tallness of the backpack is very obvious.
I did like the stretch non-zippered hipbelt pocket, as it allowed my larger phone to fit in vertically for quick access, or horizontally for a more secure but still quick to access fit. I do wish both hipbelt pockets were a bit bigger.
Overall I would recommend this pack if you need a ventilated back panel - this is unmatched, especially for the weight. Otherwise I think there are much better cottage gear options out there with better functionality. I really wanted a pack with a ventilated back, but ultimately the other shortcomings were too much. Back to my old, trusty, and loved to death Mariposa!

Most excellent light weight and versatile pack!
10 months ago
I hiked for a month on the Camino Frances in January 2024, 300 km. This pack was awesome! You don't need to fill a pack to capacity...Carry what you need. This pack adapts to all pack capacities required. I had days hiking in 28F temps when I wore everything and days near the coast at 55F where I carried everything. Just a great companion on my journey and very simple.

This may just be the Ultimate Backpack!

It's heaven. Put in the 22# of rock climbing rope and gear I had in the gold-standard of comfort: the mighty Atmos 5; and the Exos Pro 55 was even MORE comfortable. And nicely flexible too. Only design flaw is the compression straps zig zag over the outer dual access side pockets. When cinched it prevents taking the water bottle in or out. Easy work around: knot the strap under the second attachment point to disengage the lowest segment. Compresses the same and no blockage of the bottle. A more durable material on the bottom should have been used yo prevent wear. Would be worth the 1/2 oz difference. Other than that, this may the ultimate backpack!

Comfortable

Had the opportunity to finally get this pack out on the trail: 4 days, 40 miles, and a total pack weight of 34 lbs. (1) A 2lb pack is remarkable light. (2) Thought it handled the 34lbs quite well (though I'm working on a lighter pack). (3) Why this pack over other lightweight options? For 2 key reasons: 1. for over 25 years - my packing system has included a top lid and 2. Osprey has been a reliable brand for me. (4) For me - good adjustability (I have a longer torso). (5) Large stash pockets. (6) Seems durable (though I didn't throw it down any rock slides to stress test it...). (7) Overall - this pack works well for me. Hope that helps.

Great except for the hipbelt
1 year ago
1" webbing hip belt is absolutely terrible. If you are going to have a hipbelt to distribute some of the load it should be comfortable. If it doesn't serve a purpose then why have it. The current 1" hipbelt is there for "show" only. When you put it on and snug it up to distribute some of the load off your shoulders, if feels as though you have a skinny rope digging into your abdomen. This is further amplified by the wings being so short. For reference, I am 6' 160lbs. This will likely be much worse if you have a larger waist. Why they chose to not use a bit of wider webbing there at the expense of a couple grams is beyond me.

Great pack

I purchased this pack in March 2023 and have taken it on multi day trips, as well as overnighters. Pros: No problem carrying my gear and food for a week, plus food for a dog. It's comfortable, light and breathable. Love the hip pocket without the zipper. Perfect for quick snacks. Cons: the edge seam running horizontal across the top of the large, stretchy pocket on the outside of the pack is starting to fray. This area has not gotten a lot of rubbing or abuse. It generally holds a visor. Also, the small toggle type fasteners that allow you to adjust the pack length came out of the slot a couple times when taking off or putting on the pack. I ended up taping them.

Great backpack with some minor caveats
1 year ago
I bought this pack for a Colorado Trail thru-hike and used it for ~500 miles over a month. Pros: Seriously light pack for how big it is. I felt that it was supportive for pack weights under 30 lb but definitely noticed the pack with anything heavier. Contrary to other reviewers, I found the side pockets to be perfect for my 1L Smart Water bottles. The pack seems very durable. Cons: Like other reviewers said, one of the toggles for the suspension adjustment kept popping out which would make the shoulders asymmetrical. This is a design flaw and is my only complaint about the pack - it can be adjusted for by adding something like a rubber band wrapped around the toggle to keep it in place. I also found the pack to be fairly squeaky but got used to it pretty quick. Overall I would purchase again.

Great Pack

After 40 years of backpacking and having gone through 5 different packs, I think Osprey has hit the sweet spot with this pack. At just over 2# and a very adequate 55L capacity it still has great features. I am 6’-1” and 195# and the L/XL fit great. I had it loaded to 30# with no problems and I am sure it could handle another 5#, or maybe more. The quality of construction is great, with a lot of consideration to detail; such as small loops to slip straps through so they don’t flap about. The side pockets are nicely sized and make it possible to access a water bottle (Nalgene or Smart) without taking off your pack. A large Bear Vault canister fits vertically or horizontally. The belt pockets are set back fairly deep toward the rear and while access is not that difficult, closing the zipper is a little tricky. I am a little concerned about durability. That’s obviously the trade off with a light weight pack, but the thin back membrane is stretched across the frame in such a way it is worrisome. Also, the base of the pack is made with the same material as the rest of the pack, and while it is doubled over, wear is likely. Time will tell. Right now (3/23) the pack has only recently come out so waiting might not be a bad idea, if you can. A couple of ideas that would make the pack better IMHO: Add a mesh pocket under the integrated flap jacket (which seems like a no brainer to me). Use clips to attach the lid to the pack, with the direction of the clips reversed on each, then the lid could be used as a fanny pack with an attached belt (why don’t all manufacturer’s do this?). Add two small tie off loops on the base, opposite the ice axe loops so you could more easily attach something to the bottom of your pack (I’m thinking camp shoes that also tend to protect the bottom of the pack, but many like to attach their bedroll here).

Flawed engineering in the torso length adjustment
2 years ago
I would like to echo a comment made by Jeff below. I generally like the pack and found it comfortable at 30 lb loaded weight on a 7 day trip. EXCEPT: The torso adjustment feature is terribly flawed, so much so I doubt if anyone in Osprey field tested this pack. There are five possible settings that allow one to adjust the shoulder strap length to torso length. My fit is to setting four. On the first day out my left shoulder was rubbed raw by the strap -- throughout the day I repeatedly adjusted the lifters and various other items to relieve the pain. That evening I examined the pack carefully, discovering that the left shoulder torso adjustment had moved from slot four to five, making the pack hang from my shoulders in a highly asymmetric way. Once I discovered the reason for the pain, I monitored the pack, finding that this scenario repeated several times a day -- the toggle would displace on putting on the pack, or if one had to do anything involving extra motion, like climbing over a downed tree. Each time I would put the toggle back in slot four. In my view Osprey should recall this pack: it would be easy to design a clip that would prevent the toggle from jumping from one slot to the next. REI should require they do so, as a condition for selling this pack in the future. I have used Osprey packs of various kinds, but never previously encountered such ah obvious design flaw.
