Is this more of an outdoors camping backpack...

Is this more of an outdoors camping backpack or would this be good for a couple week long trip in Europe? I was also wondering if there was a way to put locks on the zippers?

Best Answer Responded on

Hi Sutton02,

While this backpack is best suited for typical outdoor backpacking, I would absolutely recommend a pack of this volume for a trip to Europe depending on how much gear you are comfortable lugging around. My boyfriend and I did a three week trip through Western Europe a few years back and found that his 75 was ideal, and my 48 was wayyyyyy too small.

As for pack locks, Safe Skies Luggage Locks and Travel Sentry make some TSA approved locks, but a friend turned me on to the Pacsafe Anti-Theft Backpack/Bag Protector ( and I feel like my gear is super safe, especially in some of the seedier hostels.

I hope that helps and if you have any follow up questions just shoot me an email at or ask for me on LiveChat on Wednesdays and Sundays!

I have generally found that in a backpack for travel in civilization, I favor something with more organizational features (more pockets, more dividers, more structure) and yet also something with a clean external shape (so it doesn't get hung up on door frames, get caught on things, etc.) I care a little less about weight of the pack, hydration sleeves, etc.

For trekking in the woods, I care very little for pockets and organizational features and I'm willing to let the outside of my pack be a bit more of a yard sale, with things strapped on in all sorts of configurations. I care a lot about weight.

So... I guess my point is this: think about how many times you're going to be in and out of this thing each day. Think about whether you're going unpack it completely each night, whether you're going to want to stuff a donut in an easy pocket, keep train tickets handy ... and where you will put your camera... and how will you access that camera while you're wearing the pack.

I realize that's not a terribly specific answer, but I hope it helps!

Probably too late to chime in, but I have found that the difference in traveling around (where ever is carrying a tent and sleeping bag. I have been all over the world. Freezing my ass off in my sleeping bag in mountain ranges of Africa and south america and burning up in the lowlands with the same gear. If you are carrying your own outdoor sleeping bag, go bigger, if just carrying sheets for hostels, you can go smaller. I barely carry cloths a few pairs of the basics - most of my pack space is taken up by local specific gear (snorkel/fins, climbing harness, whatever and camera and medical gear. )

Hi, I need to know if this backpack is waterproof please. Thanks !

It's not. It's very rare to find a backpack that's fully waterproof. You'll have to buy a rain cover to keep things dry.

It is based on your hip size and torso length. If you click on the size chart button above it will show you the chart for what each size corresponds to.

GEAR REVIEW: Osprey Xenith 75 Backpack

After miles of testing, I really like this pack. Check out my full review of the Xenith 75 in this video.

External Hydration Question

I really...

External Hydration Question

I really like everything I'm hearing/reading about the Xenith series from Osprey. I am particularly fond of the external bladder (I have been wondering, for years, why the haven't done this sooner); however, I would like to know how easy it is to refill the bladder with a full, compressed pack? I'd hate to spend $300+ on a pack only to find out I'll still have to contrive my own convenient external bladder so I don't have to unpack my pack every time I want a refill!

Responded on

Hey James,

The external hydration sleeve is more convenient, but not necessarily easier to remove, refill and replace. Getting it out and back in is no easy feat with a fully loaded and compressed pack. Lots of people leave the bladder in place and use a quick connect coupling on their drinking tube that mates with another coupling installed on the outlet tube of their water filter system. Still, release your compression straps first. So much easier.

Best Answer Responded on

Hey James! Thanks for your question. I have the women's Xena from Osprey's Xenith series. I find that it is super easy to remove/re pack the hydraulics hydration reservoir from Osprey into the external bladder compartment. This hydraulics reservoir has the ridged pack so it really helps slid the reservoir into the external hydration sleeve. I have other reservoirs that don't have the hard back and it's a joke trying to get those types of reservoirs into the external sleeve. I highly recommended this pack, you will love it! Happy Trails!

Phil... Joelle,

Thanks for the responses! I didn't realize there was a special Ospry bladder, much less that it had the rigid "backer plate". I do like the idea of modifying the quick connect couplings as well. Simply decompress, fill, and recompress. Easy money! Thanks again to both of you for taking the time...
