This expandable travel backpack was exactly what I needed! It had plenty of space to pack all my baby’s clothes, and the practical pockets provided extra storage for essentials like diapers and wipes. I also loved that it fit perfectly under the airplane seat, making travel so much more convenient. The quality is great, and it’s super functional .Highly recommend!

First of all, let me say that I love the general idea of this kind of bag, and have a smaller one at ~ 2/3 capacity. Looking to upgrade that, I must stay within Frontier's personal item dimensions, as most traveling thru CO know; I expect it to fit the gate bin. So I sample packed it with everything for a 3-4 day trip. I appreciate that it mostly held the squarish shape like a real suitcase. Comparing it to a few others, I also appreciate the velcro strap over the laptop slot (even if used for maps & papers), and the thick back packing, as well as the full sized front sections (which I will leave mostly empty for boarding except maybe a magazine and snack; can't make anything bulge to fit dimensions). In trying it on with about 20 lbs of stuff, it was actually comfortable for my 5' curvy frame.

A very convenient backpack. I use it on short business trips. There is a compartment for a laptop, convenient packing of personal belongings, like in a suitcase. Many compartments for necessary small things, a pocket for a bottle of water or an umbrella. Very light, fits comfortably on my back. Can be taken on a plane as a cabin luggage.

No charging port! Area on outside marked for it, but its empty. Still like the bag though. A lot of pockets and is just like a suitcase when open

Been traveling a lot lately and been using a back pack for the 14x18x8 under the seat bag. I thought I need to buy a bag that is designed with these exact dimensions. This bag fits this under the seat design perfectly. The company made a bag to be put under a seat and used the dimensions to get the maximum amount of usage of the space.It works perfectly.

This product was just what I needed for a carryon. It was put by my seat on the plane. It had a secret pocket, laptop pocket, paper or magazine pockets and plenty of room in the suitcase area for two day of clothes. The plus would have been to have wheels, but the grandsons helped me by carrying it. Definitely sturdy! Good buy.

First off, I'm very picky. I spent a ridiculous amount of time combing through all the fine details, photos, and reviews for dozens of very similar bags. In the end I chose the WANDF backpack and I'm glad I did.What I was looking for:~A compact backpack that met personal item size standards on Frontier airlines (note that not all airlines use the same size standard)~A fairly clean exterior to minimize chances of straps etc snagging under an airline seat.~Numerous well thought out compartments with one large main compartment that opened fully similar to a suitcase.~At least one hidden pocket on the exterior for valuables.~A pass thru port for a cord from a power pack with a reasonable way to secure that power pack inside while still being easy to remove the pack at TSA if needed.~Stowable or at least well secured backpack straps when they are not in use.~Durable materials.~Comfortable to carry.~Bonus points for colors I actually like.This bag nails virtually all of those wants.~In its un-expanded form it does meet personal item size limits on Frontier. When I arrive, if I want to shift things around and use it to carry larger items by expanding it, I also have that option.~There are numerous pockets and yet the exterior remains fairly smooth and free of snag points. There's even a wet pocket should I need to stash a damp swimsuit or something similar without it completely messing up everything else in the bag. The main compartment swings all the way open (after releasing cinch straps and unzipping) which makes packing easier and facilitates TSA checkpoint. Two zippered pockets inside the main compartment (one mesh, one nylon) offer places to secure small items. A large laptop pocket at the back has ample space for a laptop and other items. The water bottle pocket is a bit odd... I would have preferred it to be open mesh... but it is serviceable.~The hidden pocket on the back is in the typical spot (low back area) but the zipper tab can be pushed below the padding enough to truly render it invisible to all but the most determined scrutiny which I like for added security. Despite this it's extremely easy to open when need as well. There is a second small exterior pocket which is not technically hidden but is not overly visible on one side of the pack which gives me an additional location to stash small flat valuables.~The outermost pocket on the front has a rubber pass thru grommet that easily allows a usb cord and/or headphone cord to fit through. The pocket itself is big enough to hold both of my rechargeable battery packs without too much extra space, so they don't slide around and get banged up. The pocket is easy to access for fast removal at TSA if needed. I personally prefer a pass thru port over the built-in connector (hard connector port that you plug battery into on inside of bag and then plug phone into on outside of bag) that some bags have because I depend on my battery pack charging my phone as quickly as possible. Built-in connectors are often of low quality and add a "slow point" in the charge circuit that I just don't find acceptable. Simply passing my own quality high speed cord through the rubber grommet of this bag assures that I get the fastest charge possible.~Although the WANDF bag does NOT have fully stowable backpack straps, it DOES have a clever way of securing the straps when not in use that works fairly well. The trolley strap on the back can be unhooked at one side and then re-secured OVER the backpack straps to hold them snug. The trolley strap connector is a little difficult to unhook at first, but with practice I got the hang of it.~The fabric the WANDF is made from feels tough but nice. Time will tell if it is truly durable but it certainly looks and feels the part. I've owned many bags that didn't seem anywhere near this durable that I paid far more for. So my hopes are fairly high that this will hold up.~The WANDF is generally comfortable to carry as a backpack. Straps are well padded and the back is nicely padded with some air mesh type fabric in all the right places. I would have appreciated a sternum strap, but this is not a deal breaker as it's pretty easy to add one. I will say that the pack sits a bit high on my back (not unexpected for a fairly small pack) which CAN lead to the balance feeling a bit odd depending on how you load it. Weight distribution could prove to be important if you're planning to carry it on your back for long periods... but for short stretches while traveling it's perfectly fine regardless of how you load it in my opinion.~The color options are pretty basic... black, grey, navy. No bonus points for anything flashy. But... the grey is extremely attractive in my opinion. It has a "heather" effect to it and looks quite nice while still being basically unremarkable... and sometime appearing unremarkable is a good thing. After all, if you ever get tempted to overload this little T.A.R.D.I.S. of a backpack and try to squeak it past a gate attendant anyway, then you probably won't want to stand out too much.All in all... I'm very impressed with the WANDF backpack. It's surprisingly roomy for it's size, has more pockets than I care to try and count, seems well made, looks attractive, is comfortable, and ticked all the boxes I had on my wishlist of features for a personal item pack.

I like the space, it's perfect size for under-seat carry on personal bag. I've used it on Spirit, Southwest, Alaska, and American. Fits a notebook computer in separate compartment. Has waterproof plastic lined pocket, and plenty of space for clothes. I'd say it's perfect for 2-3 night trip where you don't want to lug around a suitcase or a roller bag. 4 stars because the position of the straps are not to my liking, but that's a minor nitpick. It's comfy enough.
