Frame vs. frameless packs

Different packs for different purposes. A framed (either internal or external) allows for a much heavier load as the weight is transferred to the hips via frame and waist belt. RS types of carryon size bags are not designed to carry that much weight therefor have no need for the frame. And a frame adds its own weight to the bag.

An internal frame will add a little weight (and take up a little space), but feel lighter (in my experience) on your back.

Most people don't need one if they are traveling light with a small bag. A rucksack with good straps and a belt will do.

However, I still think an internal frame is a justifiable luxury, if only you can get one in a small bag. Those are hard to find these days.

The MEI bag is very well made. It's material is a bit heavier then the RS. At 3.5 pounds, it's only 1/2 a pound heavier then the RS bag. It doesn't have as many pockets on the outside, so if you like having things available (sunglasses, boarding passes, gum, etc) you may have a problem with that. As far as it's size, it's 22x14x9, which is the same size as the RS convertable. The shoulder straps are a bit more comfortable, at least in my opinion. That might be an issue on a longer walk, maybe not so much on a shorter walk. The MEI straps are thicker, so also take up more space in their hideaway space. One thing to keep in mind is the packing space, they're different. Any internal frame bag has it's frame, well, internally. That means that the packing space isn't flat inside, there's a "bump" on the bottom. It's very much like a rollaboard in that sense, where the roller has the collapsable handle running through the packing space.

It really comes down to how far you carry it, and what you use it for.

Larry, we just returned from a few weeks in Europe where I used my MEI Voyageur for the 1st time. I really liked it for its easy "packability" and comfort. The waist strap is heavy-duty and really keeps the weight off one's shoulders. It was much easier getting on/off trains/planes than with a rollaboard or duffel bag. I think it's great value for the money.

Wow! Thanks for the replies and except for Frank and Adam we're from the same state.

I'm in the market right now for a pack to take to Europe and ive been around to try out all sizes, shapes, makes, internal and external frames. The Gregory z55 pack is a great option if you're looking for other options. It is a top loader and side loader for easy access to all areas of the main compartment. It has lots of room, but it can fit on a plane. Two people who have personally used the pack said they had no issues carrying it on going over to Europe and with RyanAir and easyjet. It's extremely durable and from what i've experienced the most comfortable pack of its size.

JB, that pack looks pretty big. And nowhere do they give the external measurment. Rather than relying on what the salespeople say, I'd take a tape measure to the store and measure it. If it's more than around 22 x 14 x 9 it won't be allowed as carry-on.

The frame apcks are good for hiking and long run trips because they are easier on your back. The frame will keep your back straight.
The RS luggage is an avarage product, technically speaking. It's light and good as size, but hard to carry on your back.If you only need to walk from your taxi to the hotel, RS luggage is evry good.
Some of the packs with a frame are a bit heavier, but nowadays manufacturers try to make them very light.
I have 2 backpacks that are under 3 lbs each and they both have an aluminum frame, which keep them light. The have good padding and the back straps are thick so they will do good in the long run.

Frank,
I've found the measurements online and it can be carried on, at least to NWA's standards. Also, because its a compression pack it can be as small as how much stuff you have in it. The internal frame is minimal and still allows the back to shrink a fair amount, as well as fill up without being uncomfortable.
