Summary: As you know we review backpacks A LOT. Our reviews show that Osprey's Kestrel packs are absolutely the best choice for those who are looking for a mainly hiking backpack that they can also travel with. Also, Kestrel 48 turned out to be slightly superior to Kestrel 38 (see in-depth comparison table below).
If you're looking for a mainly travel backpack that you can also camp/hike with, make sure checking our Osprey Farpoint 40 Review.
Differences: Besides extra 10 liters volume, Kestrel 48 has a vertical zippered side pocket and an internal compression strap in addition.
We've been buying backpacks online for years and never had any problems. Before you buy, do make sure to check the seller's return policy, but you can you can almost always return an unused pack within a certain time frame. If it doesn't fit quite right after trying it on at home, you can always return!
In conclusion, if carry-on compatibility isn't vital for you we recommend Osprey Kestrel 48 | from $103.99 (women's counterpart Osprey Kyte 46 | from $143.95 because of its (1) extra zippered side pocket and (2) more capacity since having the additional space and not needing it is always better than not having additional space but needing it!

Volume
10 Liters of difference is important if,
- You're traveling with nothing but your backpack.
- You're going on a multiday hiking/camping trip.
In both cases I wouldn't recommend a 38 Liters pack for most people.
That said, if you aren't like most people and usually pack few items, 38 liters would perfectly suffice.
Now, you may be thinking:
- "But I'm not sure if I need that (46-48 liters) much of volume - and I'm worried about ending up not filling the pack completely and having it annoyingly wobble on my back all day long."
Actually it's not a problem. Using the red internal compression strap at the top entrance of main compartment, you can easily cinch the load down and stabilize it vertically.
Available in both products.
What's more, you can shrink the pack from sides as well using dual upper and lower straightjacket compression straps.
- "And what about carry-on status? Are these packs allowed?"
No-one can guarantee that. Different airlines have different standards. Even the Kestrel 48 can be allowed when the maximum allowable size is supposed to be 22x14x9 inches because it's usually down to individual staff... Just like my 65 liters Deuter pack (yes, I'm serious).
Other times, though, you'll be made check it in and pay the additional cost. That's why I always recommend you to check the carry-on regulations of your specific airlines.
Organization
Kestrel 48: 2 hip belt pockets, 2 top lid pockets, 1 vertical side pocket
Kestrel 38: 2 hip belt pockets, 2 top lid pockets
Ends of side pocket are shown with arrows.
If you have a fair amount of items that you'd like to have more readily available, you'd make quite a use of this pocket - especially during outdoor activities.
My biggest gripe about Kestrel 38 is that it doesn't offer any front or side pockets.
Colors
Both packs are available in Ash Grey, Dragon Red and Jungle Green colors:
Kestrel 48.
Kestrel 38.
Conclusion
In addition to 10 liters of volume, Osprey Kestrel 48 has a side zipper pocket and an internal compression strap which aren't available in Osprey Kestrel 38. Other than those, they're identical.
If you don't plan on participating lots of extended outdoor trips (2+ days), you can go for Kestrel 38. If you're looking for a more versatile, do-it-all pack for both outdoor events and traveling, I'd recommend Kestrel 48.
