Inexpensive carry on for air travel

Looks fun and seems to be fine... I bought it as a smaller carry on for air travel. Haven't tried it yet, hope it holds up.

I bought this for my first plane trip in four years, a three-day jaunt to Texas.  Since I was flying United and also had a connection in a smaller regional jet, I felt I needed to get something that was small enough to fit easily in the overhead bins (yeah, I'm a little paranoid).  Even though space was nearly gone, it fit easily while all the folks with rolling suitcases had to gate-check.  Score!

The bag itself seems pretty sturdy and has a good number of pockets to hold toiletries and accessories.  It looks reasonably classy even though the leather is patch leather.  The fact that the handles attach together easily is very nice, but the shoulder strap isn't exactly comfortable if the bag is heavy.  It's a bit short and is simply a narrow band of leather, but you can detach it at will and stow it in the bag if you like.

There are many times when you are forced to check your carry on bag because the overhead bins get full.  This bag will always fit under the seat in front of you.  It seems too fragile to check, but because it fits as an under the seat bag, you will not have to ever check it.  It is roomy enough to put all your electronics and other items like medications and provisions if you get stuck overnight.
I just took a long trip and I was even able to carry it on very small airplanes and it fit every time.
The only thing I do not like about it is the front zipper can only be closed in one direction.  The other zippers can close both directions.  The wheels work well and the handle is nice and tall for tall people.  It is pretty well made for the price.

Pros:
Very light
Absolutely no worry about it fitting in even small overhead spaces
Very reasonable price
Case, zipper, inside compartments, shell all seem fairly durable and have held up well over a dozen trips (around 50K miles)

Cons:
Fairly limited space. I've had to generally travel business carrying my business jacket outside of this luggage--I noticed the airlines seem to let much larger bags on without complaint/forcing check-in. So you are in compliance with this bag, but not sure how worthwhile that is given the limited space with it.
After second trip one of the four wheels got gunked up (just from regular airport rolling use) and froze. I cleaned out what I could see and oiled it so that it functions OK (squeaks sometimes which is not great).  But it would be better if wheels were more resistant to environmental conditions in typical modern airports (e.g. SFO, SJC, JFK, DFW, AUS, LHR, Frankfurt, Copenhagen, etc.)

I got this bag as an easy-to-carry bag that i could stash under an airline seat.  Everything I could want on the flight was easily accessible.  The organizer pockets are great, my water bottle fits great in the side mesh pouch. The flexibility of being either-sided is awesome (I'm a lefty).  I knocked the cell phone pouch off a could times when wearing with another bag, but that should not be an issue very often.  Color is great, the zippers are nice and chunky/solid, and this bag is very reasonably priced.  I managed to carry a small roland cube amp in this with no problems, which is more than a little weight. The laptop section is pretty small, I can just barely get my Lenovo Yoga in there, but it does work with a little angling.

Worked great as a carry-on bag.  The small is a good size - not too big, not too small.

For the price I thought this sports bag was just what was needed for weekend get away but also small enough to be used as a carry on if it is not fulled completely.  The side pockets are nice for shoes and other small items.  I think it for the money it is made pretty good but I am not stuffing full which I am sure may cause stress on the straps.

This bag fit the need it was purchased for.  Will hold 5-8 garments and very useful for car trips.  The fabric is sturdy, but is too thin for checking on a plane.  For the price, you can't do much better.

If you're looking for a relatively inexpensive, lightweight case. . . This is certainly one to consider.  It has some padding, but is certainly not a heavy-duty case.  There are a nice number of pockets all around.  There is a strap, on the back, which will fit around most luggage handles, which comes in very handy when traveling.  This is a very simple case, and thats all I need.  But if you're looking for some real protection, then youll probably want another case.

I purchased this bag for a flight I have on Spirit airlines. I was able to get everything I needed into this carry on. The materiel seems pretty decent. I did not overpack my bag. For a quick trip this is perfect.

An inexpensive travel set for air travel, meets all the airlines' latest size guidelines.  Won't last long but I don't travel by air a lot.  Shop;ld hold up until the next downsizing of luggage by the air line regulations.

Stylish, lightweight and just enough room for a 2-3 day carry on trip.

Good carry-on suitcase. Handle gets a little wobbly after a while.  Looks lovely.  Sufficient space for short hauls. Toting it around is smooth and effortless.

Great little carry on.  Easy to pack and holds an amazing amount of clothes for its size.  Handles with ease whether rolling along or putting in an overhead aircraft bin.

This worked great for my carry on bag or even to bring along in case I need more room from shopping.

I bought this backpack for an upcoming trip and it worked out well.  It was lightweight and accommodated everything I needed as an under-the-seat bag on an airplane.

This is a lightweight, light-duty, book-sized backpack fit for a particular purpose.

The "frame" is 15.5 x 12 x 6", which expands to about 17 x 13 x 7.5" when moderately packed.  That size range, around 36 total linear inches, qualifies as the personal item, carry-on, for most airlines. It will fit comfortably under the airplane seat in front of you because it is not overly thick. It is the right size for a light trip around town or campus. The bag weighs about 15 ounces.

It's MADE IN CHINA, 100% polyester. While not the higher quality material, nylon, it looks well-constructed.

It has the chemical smell that items like this often have, so be sure and air it out first and move the silica gel packet that comes in it around to absorb those odors.

Several features make this a useful bag- a divider in the main compartment to separate one or two books or a (small) laptop computer plus three internal pockets and two pen slots. There are two outside side pockets, handy for quick access. The backside compartment, however, is limp and does not use available space in a helpful way. There are no organization options in it. E.g., putting the pen slots there would make them more accessible and better safeguard against an ink blot. Also, it would be helpful if there were a key clip somewhere in this bag.

Another feature of this bag I appreciate is the light-color interior. It makes it easier to find items in the bag due to the color contrast.

The straps have light padding and fit slightly tight- fine for about 5-7 pounds of cargo, but the small shoulder straps might start to get uncomfortable after that. This bag really is designed for light weight. You might be surprised how much you can get in an airline personal item carry-on with 5-7 pounds if you pack carefully.

Because this is the right size for an airline personal item, or for a light daytime trip, it's useful for purpose. Four stars.

To be five stars, the backside outer pocket needs improving, symmetrically and practically.
