Rated 5 out of 5 by from Great Traveller This pack worked extremely well traveling to Korea. On my previous journey I had to check my roll on and it was stolen. This carried just as much stuff but fitted very easily into the overhead and could just fit under the seat if necessary. It was also easy to carry on and between buses and trains on arrival. It distributed the weight well so that it was pretty easy for me a 60+ woman to carry. It contained all the essentials I needed to teach including a lap top.It also came in handy carrying things back and forth to the university.

Rated 4 out of 5 by from 2 week trip in Europe I used this bag for my sole lightweight travel bag in England and Ireland for two weeks. It was perfect. Required some skillful packing and I did purchase a waterproof cover from REI separately. It fit on the budget airlines with their small carry-on size. Overall a solid purchase, just wished that it was more waterproof, which was easily remedied with the waterproof cover.

Rated 5 out of 5 by from pretty close to perfect I looked long and hard for a backpack that would serve as both a lightweight travel bag and an everyday commuter bag—it's a tough bill to fill. I looked at many brands (e.g., Dakine, Trager, The North Face, Ogio, Tom Bihn) and did test packs at home and in stores. I blogged about my extended search for the perfect backpack and had begun to lose hope. When an REI employee showed me this bag and I did a test pack right there in the store, I was blown away. There was plenty of room for my lightweight travel items (a long list including clothing, a down parka, laptop computer, tablet, toiletries, and the like), with a surprising amount of space to spare. Even fully loaded, the bag felt rather light on my body. I'm not a tall gal (5'4" on a good day) and have trouble with some of the bags in this travel/commute category simply not fitting me comfortably. The Osprey Ozone 35 isn't perfect in this regard but is a far sight than anything else I experimented with. This bag has external water bottle pockets—a feature missing from a surprising number of bags in the travel/commute category—while also featuring an honest-to-goodness backpack suspension system. I chose the summit blue color, which is just stunning and a good complement to the lime green of the bag's interior spaces. My local REI carried only the black and hoodoo red bags in the store, but ordering online was a breeze and delivery was quick. I'm still learning the best packing strategy for my individual needs. The bag doesn't open flat for easier checkpoint/TSA screenings, but I don't think that will be a problem. I'll probably sew in some loops or rings in the interior pockets to assist with the organization of smaller travel pouches and cubes, and I may try to rig up a daisy chain on the bag's exterior. I will do a video review of this bag soon.

Rated 5 out of 5 by from Good travel backpack I bought this bag a few weeks ago and I just came back from a two-week trip to the Riviera Maya with it (Yucatan peninsula). I only ever travel with a carry on because I don't want my stuff lost. It fit everything I needed and then some. I actually over packed but I still had space left to fit my DSLR in its case. I love the pockets in the front that organize everything so well! I don't usually travel with my laptop since it's for adventure, not business, but I was able to use the laptop sleeve to stick two pairs of sandals in. It also has a tablet compartment, which I didn't use for that since I had a small purse-like bag for my tablet and wallet, but it was nice to be able to keep my cell phone safe in it, since I didn't want to use it abroad. When you're using the compression straps on the side you can't carry a water bottle in the sides, but I didn't use them for that anyway, I stuck in an extra pair of flip-flops in the sides on the way back. We had to walk a fair amount with the bag full and it was comfortable. I originally wanted it in blue, but they don't carry that one in the stores so I got the black one. I'm really glad I did because the blue one seems a bit loud when you want to blend in, plus I don't want it to look dirty too fast. The only thing that I don't like is that it doesn't either lay flat or open from the bottom as well. It's kind of a pain to get something you need from the very bottom of the bag, perhaps if you use packing cubes or something to separate your stuff this may not be an issue. This one doesn't have the separating part at the bottom, which I wanted originally, but since it cuts space from the front compartment, I'm glad it doesn't have it. The only other thing I would’ve liked on the 35 that the 46 has is the ability to hide the straps in the back when you’re not using them, but it’s really not that crucial. All in all, I really like my backpack and I hope it lasts a long time!

Rated 5 out of 5 by from Excellent Everyday Pack This is an awesome backpack for everyday commuting/working/traveling. I work in IT and I carry about a 13"Macbook Pro, a varying number of notebooks and folders, a 1L water bottle, and a small organizer containing drives, tools, etc. I am often walking over a mile between clients in the city and this bag feels weightless with often 12+ pounds in stow. I'm 6'2 and a bigger guy- this pack fits me perfectly has room to expand. The cinch straps on the sides and on the shoulder straps allow me to get it snug against my back making it very comfortable to wear and carry. The laptop sleeve can accommodate up to a 15"laptop- i tested it out by throwing a larger Dell laptop in there and it fit without a problem. The compartment with the laptop sleeve also does not bend or distort any papers, folders, notebooks, etc. that are placed in it. Very big plus. The large compartment has space in front of the laptop sleeve that you could easily throw a jacket, hoodie, or weekends worth of clothes into. One of the best things about this is that the bag doesn't sag and pull on your back. It maintains its shape and keeps the weight nice and even. The front compartment has a few small organization and mesh sleeves to put things in. Pretty good for a few pens, flash drives, externals- but I recommend getting something like a personal organizer that zips up if you have a bunch of small items that need secured. the front compartment is pretty deep so having something like that in there won't interfere with anything else. Theres also a small zipper compartment tucked behind the organizational part that fits a bunch of smaller items as well- usually keep some granola bars in there. There is a padded tablet sleeve thats pretty spacious for a table, or in my case a charger, rechargeable battery, work phone, and keys. You can fit a full size iPad in there without a problem. Filling it with bulkier items doesn't distort the shape much either. I will also be using this backpack for a simple overnight or weekend travel pack. Even with all the things mentioned in it- I can still fit 2-3 days of clothes into the bag along with all the essential overnight bag things. This is truly the "one bag" that you'll find is useful for anything and everything. Overall this is the most rock-solid everyday backpack I've ever owned. Highly recommend for anyone that commutes, does a lot of trekking around the city for work, for students, or for weekend travel. I couldn't love this pack more. On top of all that- it has Ospreys incredible lifetime warranty. Far exceeded my expectations. I got the black one with the green interior- it looks awesome.

Rated 4 out of 5 by from A good, not perfect, bag for most occasions I have waited almost an entire year to review this product as I really wanted to make sure the review reflected most use cases and not just initial impressions. With that in mind, I offer the following thoughts on this bag: I like the size of the bag: not too big, not too small. It holds as much, when carefully packed, as my wife's 17" international size roller bag, and I don't have to lug it behind me. I can fit two weeks' worth of clothing and essentials and still have room for a 15" MacBook Pro and a full-size iPad and a mirrorless camera system in case with lenses. That's a lot of stuff for one bag to carry, and that's why I bought it. The size is just a wee bit too large for an about-town bag, though. If you don't pack it right, you lose things in the bottom. And if you're only toting a few items around on a day trip, it's a bit more bag than you need. I often find myself unpacking the bag after arriving at my destination and leaving it in the room when going out for a photo shoot or a hike. It's just too big for that purpose. Another issue, as mentioned by someone else, is the terrible water bottle holder pockets. They're far too big for a typical water bottle, and my Nalgene 32oz fits with room to spare. They're also not nearly elastic enough, so that any water bottle will slide out of the pocket given any bump on the bottom of the bag. I've taken to carabinering the water bottles to the compression straps, which is not ideal but at least saves me from losing a water bottle. Finally, the backpack straps, while very comfortable under load, don't have any webbing loops or anything at all on the straps. You can't connect a camera harness or even a caabiner for a phone holster or anything. You've got the straps and nothing else. Seems like a waste of good functional space. In general, however, I am more than happy with the bag. It does what I wanted - moves my gear around the world in a way that I know is safe, and does so with no complaints. A few minor quibbles aside, it's a great travel day pack. Just remember it's more of a "travel" pack than a "day" pack.

Rated 5 out of 5 by from Excellent Travel Pack!!! I purchased this travel pack in December 2015 because I'm going back to school, and I wanted to have a pack where I could carry all of my belongings - my Chromebook, tablet, clutch handbag, school books and more. This travel pack has been phenomenal, very easy to work with and carry!!! There's plenty of room and pockets for everything one would need!

Rated 5 out of 5 by from Kid's backpack We got this for a Europe trip and for one of our kids to use for school. It worked great no matter how much stuff he jammed in there.

Do the shoulder and hip straps of the Ozone 35 tuck away into the pack when not in use?

Asked by: mfield94
The shoulder straps on Ozone 35 Travel Pack can not be tucked into the pack when not in use. The Osprey Ozone 46 however does have this feature.

Does this backpack fit well under airplane seats? When full, about how heavy is it?

Asked by: Always in Sandals
The Ozone 35 will measure 19 x 12 x 11 inches. We would highly recommend checking with your airline to make sure a bag with these dimensions is allowed under the seat of an airplane. When filled to capacity, the type and amount of items that you are putting in the Ozone 35 can cause the overall weight to vary.
