Which Osprey pack?

I'm a retailer & packfitter, and spend a lot of time fitting these packs and many others.

The Exos and Aura frames are different, but they are similar in the design issue you had trouble with. Both have that radius down low. I have had a few women fit an Exos better than an Aura, but not often. The shoulder straps have much less curve, & I don't think your concerns would be fixed.

The Ariel is a great pack, industry-leading seller… because it fits a ton of people really well. There's only a ~1oz weight difference between volumes. A small would probably fit you quite well w/fit dialed in. The custom hipbelt molding isn't necessary for a good fit, just helps reduce "break in" time. The Ariel frame is distinctly different than the other two we've mentioned, and I think it'll work for you. No point going to the Xenon frame (or the XS, if you're @16.5" torso) unless you're planning for some monster loads.

Other more widely available models that you might try for comparison would be the Golite Wm's Quest in medium (same as normal small), Gregory Jade 60 small, or Granite Gear Nimbus Meridian Ki. Might also try a Deuter, such as the ACT Zero 55+10SL… pretty light for its size.

I suspect that a properly-fitted Ariel 65 would make you pretty happy. If you might even push that 50# max, the Ariel would likely carry it best out of the packs above… but it all comes down to fit. Since you already have the line open w/Osprey, I'd go for the Ariel and take it from there. FWIW, if it fits I'm pretty sure you could cut into it and remove nearly a pound of extra weight… if you're comfortable taking razor, needle & thread to the new pack.

My wife has a small Ariel and absolutely loves it, we looked at the Aura but she found the Ariel much more comfortable so decided to take the weight gain.

theres no way to answer that question short of trying on the packs with real world weights

the only way for you to know is to do into a store and try them all out, find friends the same length as you with different packs, or play the russian roulette online ordering game and hope you can keep returning packs if they dont work out

Thank you all for your feedback and insight.

I forgot the "2" earlier – 16.25" torso length, so quarter inch shorter than previously stated.

Brad, it looks like the Ariel has thinner shoulder straps than the Aura and Exos. Is this ever an issue for people?

The weight of the Ariel 65L is about 5% of my body weight, although a little lighter than the Stratos 40 I started with.

Looks can be deceiving? Ariel straps are more substantial than the others by a decent margin; I think most people tend to find them a little more comfortable, if anything.

The other packs I mentioned… GG, Deuter, Golite all weigh 3.5 pounds or less…

my girlfriend is tiny–5' , ~100lbs, 16.5" torso, and the only framed pack that worked was a 40 liter golite lite speed in the small size. The pack fits her well b/c of the narrow harness straps and bendable aluminum stays. Unfortunately, they downgraded the golite litespeed this year, so its now smaller than 40 liters. However, I still would take a look at golite packs, since IMO their small sizes are proportionally fitted for smaller petite women. I know they have lightweight 50+liter framed packs for women*

edit* The GoLite Quest that Jeff refers to below sounds like a good bet. Also check out the Golite Odyssey if you need mega capacity.

Perhaps the Golite Quest would fit the bill? I own the Women's medium. I believe it is around 62L. Probably a little less in reality because the back pocket becomes difficult to fill once the main pack is stuffed. I also have a short torso @ 16.5" (I'm a small guy). Also, you can find great deals on it. I got mine a few months ago for around $75 on sale.

My wife also has the Ariel, and loves it. She has the 55 liter model from a few years ago — looks like the current model adds one of those (useless) sleeping bag zippers across the bottom. Oh well.

If you think you might carry 50 pounds, this is the pack that can handle it.

Another Osprey choice would be the Kestrel series. I have a Kestrel 32 that I use for a "heavy" day pack (cameras and the like), and it fits and carries well. It has a more traditional frame design, so no little wings. The larger Kestrels have the traditional top-loading design with a lid pocket.

What about the new Hornet? I am about your size and it fits me well. Won't be for sale until spring I think, but maybe one of the larger folks who received one could pass it on to you

I would definitely take a look at at the Dueter packs. They already are able to be adjusted to fit almost anyone thanks to their unique system, and the SL versions are women specific. I love my ACT Lite (men's) because I have a pretty small torso for a guy. I would recommend researching about the SL system at their website because it sounds like they really took the time to research what characteristics women need in a pack.
