I love this luggage. I have it in several sizes.

A great surprise is the wheels. I had no idea how nice it would be to have wheels that turn completely around. It makes it 100 times easier to navigate--which is very essential for large pieces.

Another great thing is that this suitcase is made with lighter materials than most. Even in smaller sizes such as this, any reduction in weight matters as it makes it easier to handle.  Especially if you are lifting it into an overhead bin.

The telescoping handle works smoothly and is very convenient and easy to use. The smaller handles help you when you are lifting it.

I would highly recommend this to everyone.

I would really encourage you to buy luggage with spinner wheels. Once you try them I don't think you will settle for less.

There is an inner pocket that is plastic to hold things that are wet.  It comes with the quart size plastic container that the airlines approve for putting your liquids in.  Another great feature that was a surprise is that the rear wheels are larger than the front wheels--the larger wheels aid in the ability to maneuver it as you are tilting it back and pulling it.  That is not written in the description anywhere but it should be--again it is one of those features that sets this luggage apart from the competition so they should be advertising it.  But I guess it is nice to get surprises to.

there is also a handle on the bottom of the luggage in between the wheels--it seems like an odd place for a handle--but when you are lifting something into the overhead bins, it comes in very handy as you can have one hand on that handle and the other hand on the top handle.  Another nice surprise.

The Silhouette 11 Boston Bag and the Silhouette 11 Shoulder bag have a slip in their material allowing them to snuggly slip over the handle of this carry on so that you can easily make your way through the airport with 2 bags.  Since most airlines allow two carry ons, but require the second one to it under the seat, these smaller bags make perfect accessories to maximize your ability to take things on the plan but also not have to deal with 2 bags--or those bags that go over the handle but somehow twist around and don't seem to stay in one spot--making it harder to maneuver.  Amazons description of the Shoulder bag does not mention this--however, i have one, after doing extensive research, and it does have the slip just like the boston bag.

This luggage is worth every penny.

I purchased the silhoutte 10 (the previous model to this) about 3 years ago and it hasn't really shown any wear and looks and works great. In preparation for an upcoming vacation, i went to purchase the silhouette 10 again and discovered that it was no longer available and it has been replaced with this model. the biggest difference (other than the available colors) that i have figured out between the two models is that this newer one has the dupont nanotechnology that is suppose to make it more stain resistant. i haven't had this newer one long enough to comment as to if that is true, but my older one has never gotten a stain.  The material used in these suitcases (and the previous model) is much stronger and durable than the material used in most suitcases.

As for the 22" and the 20"--supposedly the 22" is carry on luggage--however, it does not meet the carry on guidelines of all airlines so you could get stuck having to check it at the last minute and paying the extra charge to check it. Also, if you expand the 22" to put extra stuff in it, it will not fit as a carry on. The 20", on the other hand, should always be safe as a carry on with the current guidelines--even if you expand it with extra stuff. And, the capacity when expanded is just about the same as the capacity for the 22" non expanded.  That is why I chose the 20" over the 22"--I want to be safe that I can carry-on the luggage on all carriers.  (You can't rely on the dimensions given for the luggage as it doesn't seem to take into account the wheels--but airlines would add on for the wheels--which is one reason the 22" does not conform to all airlines.  My 20" measures 43 linear inches  (how airlines determine whether it qualifies) when it is not expanded or stuffed.  When expanded, it measures 45 linear inches....still enough to work as a carry on.

Also, just to note that with the other sizes in this series--between the 29 and 26 there is much more flexibilty with the 29 as you can put a lot more stuff in it and yet it is sill very manageable. If i had to choose just one of those sizes, i would choose the 29. I have the 26 as well and it is fine for shorter trips, but i find that i use the 29 much more often than the 26. Most of my trips are 9-16 days long. But even with a 7 day trip, i prefer the 29. Now, the difficulty comes if you have a smaller car trunk. In a nissan maximum, i could fit 2 of the 29" along with 1 26" but pretty much nothing else in the trunk. Many people have smaller trunks than that when it comes to cars. It is nice to have the 26 available to me if i am going on trips of 7 days or less, but i personally wouldn't be upset if i had to use the 29" for those trips.

UPDATE 4/4/10:  just to add another comment about this (or the 22 inch)--the spinner wheels are awesome--but it is also awesome to have 4 wheels.  I hadn't really paid attention but we just went on a long trip and i had this and the boston bag packed very heavily.  I started wheeling it through the airport like normal (where you lean it on the back two wheels).  But it was really heavy (we put the heaviest stuff in the carry ons so that the large luggage would weigh less).  So after my arm went numb i realized i could just stand it up, keep the handle pulled out, and wheel it along beside me on all 4 wheels--way easier than two wheels.  And as i strolled through the airport watching everyone else pulling their carry ons, i was very glad i figured it out.  To use it like this, you would have to have spinner wheels--but i think that all carry ons that have 4 wheels are spinner wheels (although i could be wrong).
