What backpack should I choose for my trip?

For 4 years, I used my Osprey Ariel 65 (3800 cubic inches) hikers backpack and from time to time I would carry it on or check it. But that was before airlines became strict on carry on requirements. The last time I brought it to Europe, to carry it on, I had to basically have nothing in it (most everything was in my messenger bag, just so I could meet the requirements). So, since I loved my Osprey product and knew that I would not be able to bring my framed pack on the plane much longer, I opted for the more plane travel oriented Osprey Porter 46 (2800 cubic inches). I like how it loads like a suit case (instead my top loader Ariel), but it has adjustable straps, leveraging straps, and a waist belt for when you have to trek with it. It was fine for my 3 week Eastern european trip, although I could not cram as much in it, it was fine for my needs. The straps also can be zipped up as well. the best part is that they run $100, even less if you google shop one. Check it out. It may be what you are looking for.

Remember, a lot of European airlines go by a weight limit (Lufthansa and some others, 8 kg = 17.6#) even if the size is not exceeded. I find if I stay within the weight limit, I have no problem staying within the size. The Rick Steves Convertible has more than enough room to exceed the weight limit.

If you have an REI store near you, got and check out what they have. They will fit it for you too. Nothing worse than having a backpack that doesn't fit your body.

The man who runs onebag.com says you cannot beat the MEI Voyageur. It's made of stronger material than the RS convertible bag. The dimensions are 22x14x9 (2772 cubic inches).

I used to own the RS convertible but sold it when I got this one:

Ebags Motherlode Weekender

Another model I've heard good things about is the:

LL Bean Quickload Travel Pack

2500 cubic inches seems like a lot to me, though I guess it must be a popular size--isn't Rick's bag in that neighborhood? But less is really better, the more so if you will be moving around a lot. I'd shoot for 2k cu.

Paradoxically, the longer the trip, the more important this is. I don't think you'll need many layers in September.

Even if you don't think you care about this, do take into account airline restrictions on luggage size and weight.

As to a "different kind"--a convertible bag is pretty versatile, but you should suit yourself. I'd stay away from wheeled bags though unless you have a back problem or other special need. Wheels add weight and you can't always roll.

Rick's convertible bag is 2500 cubic inches when not expanded and 3000 cubic inches when expanded.

You didn't say what it was about the Rick Steves bag that didn't "fit your needs". At 2650 cu in (9" x 21" x 14" = 2646 in3) it's a little bigger than your 2500 cu in target. Is is too big?

The 2500 and 3000 figures I gave are for the interior capacity of the RS convertible bag as described on the Travel Store pages.

I have the TLS Motherlode from ebags and the OPEC from campmor. Either one works well. They've both been to Europe and will go again. Since I don't hike with my pack but only go from transport to room, I use a convertible. If money isn't an object, the Tom Bihn Western Flyer might work for you or the Tough Traveler Tri Zip. Check them out.

And what airline goes by "interior" capacity when checking your carry-on?

Are you looking for a true backpack or a convertible carry on? Most posts have recommended a convertible bag, not a backpack.

Osprey is top in the industry right now for true backpacks, and they make "travel" bags as well.

If you want to save money, but still have fantastic quality, look at the High Sierra brand. The Col 35 would fit your needs, and cost you less than $100. You could also look at the Summit 45 if you need more space for a few more $$.

if you are looking at a convertible bag, I recommend the Eagle Creek ORV trunk. It's not quite the same quality now that VF corporation bought Eagle Creek, but the size is exactly what you are requesting, and it does work very well.

I just got back from a domestic trip today, and carried my Kelty Redwing 2650 on to both planes--and one was a tiny commuter plane upon which many with (appropriate sized) wheeled bags had to gate check--it fit into the overhead compartment even on this very small plane. and it was more than large enough for a week way--and a weeks worth of clothing will last you forever, if you wash your clothing once a week! (or, better, daily)

I'm currently using an ebags weekender. It works fine and has held up well for at least five years (probably closer to ten years) of regular travel. It has been on trips from weekends to more than a month without a problem.

I like the compression straps and the organizing pockets on the front of the bag.

Since it's soft, and I don't usually pack it full, I've never had a problem - even on commuter planes.

The 2500 cubic inches of space is pretty standard. Most are geared toward maximum carry on size. I considered getting a slightly smaller bag (since I keep packing lighter). Any step down turns into a daypack and you lose the luggage style compartments with full three side zippers (which I like).

I'm using my North Face Big Shot. It should be perfect at just over 2000cu, since I also have a messenger/shoulder bag to use as my day pack. I really like the cushioned straps (with space technology pads) and numerous compartments. I was looking into the convertible bags myself, but since I needed a new backpack anyway, I decided to go with a more traditional model from a trusted brand.
