Bought this to travel with my daughter in Italy and Greece. Firste pic is with my boat ticket from Brindisi, Italy to Igoumanitsu, Greece. The pic shoes the day pack installed and my travel pillow strapped on. I detached the day pack often for day trips and also to get on planes and trains. With the day pack removed, the rest of pack turns into a duffle that I carried on my international flights. We went though trains, planes, boats, and buses, walked throuh Venice, Forence, and Rome, and no issues. I used the packing cubes (sold separately) to organze the inside. This has straps inside to hold the your stuff in place and also a way to hide the backpack straps when using as a duffle. Really a cool design.Will def use the for all travel like Hawaii and when jumping in my van to go!This is an extremely functional pack. I took it for a month vacation/honeymoon to the Philippines from the USA, and I loved how easy it was to organize and find stuff with it. The day pack was very useful too.I bought it to replace a (much older) travel pack that was stolen from me that I had taken literally all over the world over the last 25 years, and I found this to be significantly smaller than I had expected based on the marketing material. I'd definitely buy a bigger pack if I was to do it again. There's no way I'd fit a sleeping bag, shoes, and clothes for a week in here, which I could do with my last one.That said, it's functional and it seems to be pretty durable - there's no sign of anything about to give up or tear. I don't NOT recommend it, just make sure its the size you need.Used this backpack travel pack on 2 international trips. Had held up great. Lots of room. Love the zip off day pack.Was our first trip to Europe. Didn’t want wheels in case the cobblestone streets and stairs were problematic.Plenty of room for us to pack for 15 days and packed far too much. Also bought the one smaller for my 15 y/o.Was super light not more than 30lbs total fully packed. Great Quality.One of the best purchasesSpent two weeks in Europe, was able to get just about everything I needed in this. There is a slightly smaller version of this but would recommend getting the extra space with this! Make sure to order the travel cover if you plan to check your bag before your flight!I bought this bag system for a trip to Hawaii. The larger pack went into the overhead compartments easily and the smaller bag stowed under the seat in front of me just fine. I say system because there are two bags on review. Together the bags make one mega bag. When scrutinized individually the bags ultimately suffer from specialization- the larger bag is a cavernous open space loses practicality with smaller loads, the smaller bag is good for a day long jaunt for one or two people's stuff so long as its small.Its a solid bag system and I highly recommend it.Bought it along with the 55 a few weeks ago. If you are having trouble deciding between the two and can get this for about the same price as the 55, I'd suggest going with this, as it's slightly larger in capacity, but as some reviewers on Amazon and elsewhere have already pointed out, you really have to look for that extra 15 liters with this one.Overall,, it's a great bag! It looks good, it's light weight enough. It has zippers you can run a TSA-approed or similar lock through it. The daypack is great and has a good laptop sleeve that comfortably holds my 15 (plus) inch laptop. The daypack is also textured inside and is a bright green color, as is the interior of of the main pack.This type of combo bag is what I needed, for staying in hostels especially, so I can easily store my luggage in the main pack and lock it away or leave it on or under my bed, but can bring my pack with laptop (Macbook Air, lightweight for travel), camera, some food, etc., and not worry about leaving valuables behind. It's great to have just one bag to carry from planes, trains, and automobiles, yet containing the option of having two different function bags to use simultaneously once arrived at my destination(s).The only reason I didn't end up keeping it is I still wanted something larger, not because I needed more space to get by for a 70 day European travel trip, but because I wanted more space to bring things back home as souvenirs or for memories, as this trip is my first time going. This could easily be overkill, too, as the 80 with a piggy bag is MUCH larger than this bag. But having more space to pack for travel doesn't mean (for me) that I'll pack more things, it just means I'll come back with more (lightweight keepsakes, which I'm very much OK with, and look forward to! For a more seasoned traveler or a dedicated minimalist, you can easily pack away in this for as long a journey as you need--just wash your clothes and consider some packing cubes or some method to organize and/or compress your items and clothing.Ultimately I chose the 80, with a Quasar to piggyback as I really didn't like the Daylite Plus. But I think the 70 is great and Osprey quality speaks for itself, so I don't need to improve upon that, here.Bought this because my work assignments are invariably at clients' locations. Have had to buy a second piece of luggage (this) because the Sojourn only goes up to 80 litres and the Farpoint 65 Wheels only goes up to 65 litres. Neither Osprey or any other major manufacturer with a retail presence in UK currently have in the inventory a model of travel luggage with wheels as well as shoulder harness which is 100 or more litres. (So far have been travelling with a no-name / made in China 115 litre luggage, which after 8 years on the road should soon expire. At present there is no replacement available in the UK, only in US.)Anyway, decided that a Sojourn with Daylite pigggy backed or a Farpoint 65 Wheels piggy backed with a Daylite series of pack is not good enough, mainly because the Darlite or Daylite Plus to not have padded section for a laptop. This zipped-off 13 litre pack has given the laptop section some padding. Secondly, zipping ion and off this pack off and on the main pack is faster than detach or attaching a Daylite only those mentioned wheeled luggage.70 - 13 litres = 57. then add 65 litres of the Farpoint 65 Wheeled means I will get the volume needed for steel toe boots, inflatable life jacket, safety glasses, hard hat, coveralls, ear defenders, masks, gloves.... phew. One piece of luggage full already. Then I shall need noise meter, light meter, camera ...... for doing inspections. So I just wish some manufacturer will just make big piece of luggage with wheels and shoulder harness because Osprey, your Rolling Transpoerter 120 does not meet the spec.I'm female, 5'8 and have been backpacking with this for 5-6 months and it's been great. Really comfortable, strong and the perfect size for everything I need (I'm in Central America so a mix of beach and mountain climates but nothing too cold). I love that it opens up fully. I use it with three large packing cubes for clothing, with extra room for my laptop, toiletries, and other junk. I wish it had more internal pockets though (it just has one large mesh pocket that I'm always fishing around in).I don't find the daypack that useful as I carry a handbag day-to-day so only use it on long bus journeys, which it's just a little too small for. When I'm next in the UK I plan to switch it for a larger backpack that's a little more stylish. If it's possible to purchase without the daypack that would have probably been better for me.Fantastic product, If you are lucky can squeeze into hand baggage but make sure to take out the small bag as it looks bulky for hand hold bag. I have carried around 15kgs for my months trip and quality is fab. Please note this amazon product is not the latest farpoint product as advertised in osprey website, I guess this model is 2018 but doesn’t make any difference in build or compartment just the quality is much improved one in terms of material. I have done around 3 trips in this and twice I have put in checkin and no sign of any tear etc.An osprey for £100 is great value and the quality is fantastic. I returned mine as it wasn't what I needed. It is 70l but the main compartment is 57 and detachable daybag only 13l which is kind of the worst of both worlds when you're looking for a 70l bagm great comfort and features but a little small for 70l in my opinion don't expect to get more than one pair of shoes in or anything. Would be great for city breaksExcellent backpack looks like it will great for the job I walk everywhere for shopping etc and the capacity and comfort of this rucksack. Little disappointed that there is no longer a port for hydration pack but I have used the outer external pack with an opening in pack. Detachable pack is a really good option which I had on my old craghoppers sack which has now been retired as it fell apart and is patched up beyond recognition. The external pack can be worn on the front to distribute weight. Awesome design and build quality a must buy
