Gear Review: Osprey Ozone 18

Osprey Ozone 18In an earlier post, I mentioned I would be reviewing two ultra-lightweight wheeled bags because their weight was within the standards we normally consider.

The first is the Osprey Ozone 18.

Made of 210 denier nylon, the Ozone utilizes Osprey’s proprietary “High road LT Chassis” suspension system. This features a single tube, locking, retractable handle; an aluminum f rame; an injection molded ABS base with footbar/grab handle and polyurethane wheels.

It weights 4 lbs 2 oz/1.92kg and the packing area measures 18″ x 14 x 8/ 46 x 35.5 x 20 cm. The total volume is 2187cu in/36L. The length increases from 18″ to 21.5″ when the wheels and handle are included.



Vertical Zippered PocketEach side of the front of the Ozone has a zippered vertical compartment. There is a divider between the two so only longer, thinner items will fit. The can easily hold a jacket or sweater or perhaps an Eagle Creek Tube Cube.






External Compression StrapsThere are two external compressions straps helping to keep the bag snug and also making it difficult to open the front and main compartment zippers.





Panel Loading Main CompartmentThe main compartment opens clamshell style, has two internal compression straps, two smaller side pockets, one made of mesh, and a mesh pocket in the lid.







Zippered top pocketThere is a zippered top pocket perfect for the 3-1-1 bag and three grab handles: one on top, and one of each side.





Rear PanelIn the rear is a very thin back panel with a mesh pocket on the inside cover. This pocket could be very useful but the retracting handle takes most of the room of the pocket. Don’t expect to put anything thicker in there than an inch  or two. (This is not thick enough for a laptop.)




I was surprised how well made and sturdy this bag was considering its light weight. The bag rolls smoothly both pulling and pushing and handles corners without toppling over. I believe this bag could easily be taken as a carry-on but would manage well if it had to be checked. (Osprey has a lifetime warranty on its products so if something does go wrong, they’ll fix it at no charge.)

If you’re looking for an ultra-lightweight, wheeled carry-on bag, and can manage packing less than maximum legal carry-on, I suggest you consider this bag.

The Osprey Ozone 18 is available in light grey and light green and retails for $199. Photos courtesy of Osprey.

    For Australian’s considering this bag, just be aware that the Australian distributor of Osprey does not offer a lifetime warranty, and does not cover airline damage.

    I own 3 non-wheeled Osprey bags and they are well made, and I’ve never needed to use the warranty.

    I’m seriously debating getting these for my two kids. The four of us backpacked through Europe – us with our Tom Bihns, them with their school backpacks – it was great and I wouldn’t do it any other way. However if I was to be totally honest my youngest son in particular complained about the weight of his backpack some. And I do find my tiny under seat wheeled bag useful for work trips to cities. I’m considering having the kids use these for domestic travel only – I generally find wheels much more useful here, and pretty much useless in Europe.

    Do you know whether this bag will fit under a seat?

    I doubt they’d fit. With wheels and handles, the dimensions are 21.5 x 14 x 8.

    Hi Frank,

    I’m really enjoying your website, lots of very helpful info.

    Regarding the Osprey Ozone 36L, I contacted Osprey Customer service and they said that the max dimensions is 19x14x8 including handles and wheels. The Osprey Ozone looks to be the perfect bag for me as I’ll be frequently flying an airline that limits carryons to 20x15x8 and I’m looking for the lightest bag I can find that fits within their sizer. Unfortunately there are no stores around that carry this bag so I need to order online. I almost didn’t buy the bag when I saw your review stating that it was 21.5 inches tall, but now I’m going to take a chance. Would you mind double-checking your measurement?

    Thank you,

    I no longer have the bag.

    I will say this…l measure bags at least twice. My dimensions include wheels and handles.

    Not all manufacturers include wheels and handles and the custormer service reps may not know if they do or not. They are going by the published information.

    If you get one, let me know what you find out. I could be wrong.

    My suggestion is you buy the bag from someone who offers free returns….like eBags or Zappos. This way, if it is the wrong size, it won’t cost you anything to send it back.

    If you are interested in a couple of bags that will fit your dimensions but weight a bit more look at the Eagle Creek Activate (I’ve reviewed this) and the Eagle Creek Flatbed Duffel 20 (I have this bag, just traveled with it, and will have a review out in a few days.)
