Stratos Backpack

I have gone through several of the Atmos series with Osprey, fantastic pack. I did complain to them that, although perfectly designed to distribute weight on the hips, it was not the best pack for long wall days particularly if your route had any chimneys. Yamnuska, a big wall where I spend a lot of time, has quite a few chimneys. They referred me to Stratos which has much of the same features as the Atmos, but with a narrower profile. Supper pack. Very durable as is the Atmos. You can do several sizes, but the 24 served my purpose. Anything larger, might as well go back to the Atmos in my opinion.

I picked up this one to replace an ailing daypack that had served me well. I love this as a day pack particularly for when I don't have to carry alot. The mesh panel is awesome as I don't get the sweaty back like I do with my other daypacks. It is just a quality product and while a 24 might have served me better, the 18 does what I need it to do. I have an Atmos 50 which I step up to when this size doesn't get the job done and and an Atmos 65 for bigger trips. You can see that I am addicted to Osprey gear.
I had an Osprey Aether 60 but I must have loaned it out as I can't find it anymore. The lesson: Don't loan out anything you don't want to lose. These Stratos packs are all A1.

This pack series is smart. Worked well as a crag bag for long approaches and as a light but sturdy day pack.

I'm selling one that is virtually new (because I bought the wrong torso length) here: http://www.summitpost.org/phpBB2/viewtopic.php?t=27495

Functional and quality pack. The option of storing your hydration bladder either behind the mesh backpanel or in the sleeve inside the main compartment is a nice feature. Either option will accommodate a 3L/100oz. Camelbak reservoir.

Great little pack, perfect for bagging peaks in a day. Doesn't interfere with a helmet and just the right number of compression straps and pockets to make it useful. The hip pockets are great for a small digicam and I like the mesh back with the airspace - no more super-sweaty back from your pack!

Finding a day pack that was (a) lightweight, (b) bore weight comfortably on my hips, (c) could accommodate a 3L reservoir, (d) fit through the shoulders, and (e) fit my [relatively small] frame was a nightmare. Found this pack in a S; met all of my needs and then some. Would highly recommend. The *only* *minor* complaint that I have is that the side compression straps cover the quick-grab side pockets, which means that, say, if you want to carry your GPS in one, or anything else that you'll be using on your trek, you kinda have to leave the strap loose, which sort of defeats the purpose.

In the neverending search for a good fitting yet functional daypack, I am very satisfied with this pack. No major complaints.

I have owned the pack for about six months. I have taken it rock climbing on numerous occasions. I also used it as my summit pack to the top of Pico de Orizaba. This pack rocks in every way. It is simple, lightweight, and tough. The ice tool straps made it a great choice for glaciers and it is just the right size to hold all the stuff needed for rock climbing or peak bagging. I love the AirCore back panel. You can put more than a hydration bladder back there. I agree with Katy Y that the side compression straps are not placed in the most convenient place. On a scale of 5, this pack is easily a 4.9

This is by far the best day pack I have ever had. It is one of the few packs that will fit me correctly, and it perfectly distributes the weight onto my hips.

The very best multi-use backpack I've ever owned. This thing handles 90% of everything I throw at it. The only thing it doesn't work as well for are short day trips(obviously too big and heavy) and really long excursions.

I find that I can fit everything I need for a day out in the winter as well as technical gear for a summer day or overnight trip. The straps in the back make it easy to attach snowshoes and its got nice ice axe loops and an easy to stash trekking poles. I've even gone out for 3 days on summer climbing trips with this thing. I have to stash some things outside of the pack though. The nicest thing of all is that I don't feel limited on what I can do with this pack on. I can climb chimneys and traverse technical terrain with this pack without it snagging on stuff. No need for a seperate summit pack. The air core frame is just awesome. I no longer have my back soaking wet after taking off my pack. This thing provides plenty of ventilation. Very well executed pack.

I bought this pack for scrambling and dayhikes. Great pack, really comfy and holds enough for overnighters in warm weather. The only drawback was it is a bit wide in chimneys(and I have very wide shoulders)and it wore through in the lower corners of the frame near the hipbelt. Barge cement and some donor fabric fixed that.

I had been using a Camelback pack, and it was a decent pack, but it lacked adequate support so that it sagged a bit and became a drag on long days, and it lacked loops for an ice axe, making me use the one loop provided in a somewhat awkward manner.

After seeing a friend with the Stratos, I decided to get one, and I have been quite pleased with it. I like the top pouch that provides quick and easy access for essentials, and the side pouches are good for stashing maps and being able to grab them on the go. But the best feature is the frame, the structure of which keeps the pack from being directly on your back, which in turn keeps you cooler and distributes weight better.

The frame is also my one real complain, though, for its shape makes it difficult to pack some larger items efficiently, and it also makes it hard to store a water bladder inside with other gear. When you keep the bladder in the mesh-protected chamber, it tends to get warm due to being against your back. A relatively minor complaint, but a disappointment nonetheless.
