Osprey Talon 44

I've been really impressed by the versatility that I've gotten out of this pack. I've used it for everything from short dayhikes in the cold to weekend backpacking trips. The pack has ample storage, and the side compression straps help hold everything in place when you're carrying a lighter load. I've carried up to about 30lbs for weekend backpacking trips, and the frame and harness are still very comfortable at that weight. You would probably want a more substantial frame and harness for loads over 30-35lbs, but you would also be hard pressed to cram that much stuff into this pack.
This pack fit my sleeping bag, full tent (Big Agnes Fly Creek 3), 3/4 sleeping pad, clothes, and my share of kitchen gear for a weekend backpacking trip, with a little room to spare. The floating lid is a great feature when you're pushing the volume on this pack. Also, the side and front pockets have a good amount of stretch, so you can cram a jacket, fuel/ water bottle, etc into them, even if the pack itself is full.
The harness is very comfortable, especially in warmer weather. The hip belt and shoulder straps use a lot of mesh and light foam padding, so they're very breathable.
A couple "nice to haves" would be a daisy chain sewn onto the back and an integrated rain cover. However, with the features and weight savings when compared to other packs in the category, I'm happy to buy a rain cover and leave it at home when the weather looks good.

I have had this pack for over a year and used it for a variety of trips - camping to hiking to trips via car and plane. One can pack an enormous volume of travel or outdoor necessities if using compression sacks.
As a disclosure, I bought this pack from a local outdoors dealer in order to try many different packs.
I found the fit to be solid and form fitting to your body. With osprey, you are able to adjust the location of the main body of the pack by sliding it up or down to suit your body frame. This adjustment is possible through a velcro system holding the body of the pack to the "frame" straps. An additional adjustment moves the pack higher onto your shoulders.
The result is one of the best fits possible in mid-size packs such as the Talon 44. Take your time with it to suit your body and the pack will reward you.
The next benefit is the enormous number of options relating to external straps and hooks available on a pack this size. I can't conceive ever being able to use them all at the same time but it does give you versatility.
No wear after numerous trips and uses. I think that will be reduced on this pack due to how the fabric typically hangs on packs of this type plus Osprey uses a solid exterior material.
Overall, if you are seeking a multiple day or weekend pack for a variety of adventures than this is your pack.

I've had this bag for a couple of years now, and I can't even count how many trips I've taken it out on, both over nighters, and multidays (up to a week). Its comfortable, durable, and packable to a point.
The bag is way bigger than it looks, and packs pretty well if you're smart about it. I've read a few reviews about over packing this sucker, and it is totally true. If you don't sacrifice some weight for the longer trips, you'll feel it in the shoulders. The shoulder straps are super thin (but insanely durable), so they do dig in if the packed weight is substantial.
There was a question about living out of this thing for multiple weeks on the JMT, and I just don't see that happening, not enjoyably at least. I've taken this thing out for a max of 5 days without resupply and that was cutting it thin. I am not a lightweight backpacker by any means, so I am speaking with bias.
Durability on this pack is fantastic. You can barely tell mine has been used, and I have bushwhacked with it, dragged it up narrow ragged chimneys, and more. Someone also asked about water-proofness; grab a rain cover with this one. It isn't very water resistant, and gets heavy when damp.
I have a pretty good quiver of bags, but anytime I go out and know I'm gone for 5 days or less, this is my go-to bag.

So my torso measurement (measured with Osprey's torso measuring tool) is 20.5 inches. That's measured with my neck not bent, some manufacturers ask that you keep it bent, which adds another inch or so.
The medium/large sized talon, according to osprey's website, is good for "19 inches and up". I tried it with a moderate load and the suspension dug into my shoulders and the load lifters couldn't possibly work. Adjusting the straps up and down with the velcro doesn't help; if the height of the suspension is shorter than your torso length, there's no way for it to work properly. I'm going to buy a ULA pack instead, they make them for people in my size. Thanks for the good return policy, backcountry!
I wanted to avoid giving stars, because I'm only giving sizing info, but the form won't let me. So how about 4? Seems like a really nice pack, but I'm disappointed in osprey's limited sizing.

This pack is the exact size I was looking for. For the crag, for traveling, and for some hsorter camping trips. I find the number of straps and loops and such that cover it to be unnecessary. Other than that though, it performs as expected. The hip belt doesn't fit me perfectly (if only it could go about an extra inch tighter...5'9/145), but the pack actually still works pretty well. It's not perfect, but most of the weight stays on my hips and it is certainly a comfortable pack.
I'd say to try it on at REI or some such, but it seems to work pretty well on my traveling and climbing trips around the Santa Monica Mts thus far.

Been hiking every weekend since I received my new Talon pack. Been going on 3-7hr hikes each time and love the feel of the pack. It stores a lot and the adjustable frame is great. I don't feel the weight thanks to the lower belt and the flow through feature on the back. All in all great for the money, will be climbing Mt. Olympus in September so it should be the perfect addition to the trip.

We used the bag as a carry-on luggage and for day hikes during our trip to Europe. Airlines did not object to the size and it fit easily in overhead compartments. The bag was easy to carry and kept my back cool while hiking in warm Italy and the contents dry in rainy Norway. Good balance and adjustable with easily accessible compartments. I was even able to fit my 17" Laptop in it.

I did a month-long tour of Europe, and a two week trip to Peru bringing only this pack. It was perfect, and easily fit everything you need if staying in hostels. Despite loading it to capacity, it always felt comfortable. The pockets on the hips were great, as they can hold a point-and-shoot easily, allowing for quick pictures when I came across wildlife. After this pack, I'm sold on Osprey for life.
