      Anyone here did not receive their bag like me?

    3. Ray Law on

      Received the bag and tried to use as my daily commute bag for a week. Comfortable, thin and slick design. The cable compartment is big enough for my 15” MacBook charger and all cables.

      However, there are a few quality issues, scratched handle, and bad inner pocket stitching which I don’t expect with bag in this price range.

      @John. Thanks for the positive feedback, we will look into the hooks in the future.

      @Gavin. Thanks for the news!

      @Joshua Corin. Good to hear that you are happy with the bag. Thanks for being a part of this project.

      Same my blue bag has arrived as well, looks awesome, the material and finish is a lot better than i expected. The organised pocket material inside the front pocket is really nice and made out of the same material as the rest of the bag and that front pocket is massive.

      Early feedback for improvements on the next iteration would be to go for some larger YKK zippers, these are a little small for my liking and not as smooth I would like.

      There are a lot of zippers so some options for colour coding some of the pulls so you can distinguish easily between them would help.

      As others have said the G hooks are nice but a little difficult to remove from the tabs so maybe some refinement on the shape of the G or the tab/hook size to make it easier (i'm a fan of G hooks over plastic buckles though)

      The bottom front pocket is a little small depth wise so not very useful for me, for example I can't place my separate cord/cable bag in here because it's too thick.

      I'm going on a trip next week for a few days so will report how it performs after the trip.

      Overall it's an awesome bag, the colour, style, quality of workmanship and functionality are all top notch. It's also comfortable from the quick test fit i tried as well.

      I love that I can fit my laptop and ipad's in the laptop compartment and the quick access pocket is very useful.

      Thanks for having us on this journey!

      @James, how do you plan (or how would you) swap those compression strap hooks?

      James Hatch on

      Spent some time with the bag last night getting it ready for my first trip with it. I've taken care of the dangling straps and figured out where things go. I'm not swapping the flap compression hooks yet - I have a clip version that might be easier to hook/unhook. Except for things I do to all luggage (like taming the straps or adding attachments to hold a water bottle, etc) I won't make any changes until I've used it as designed for a few trips. In the end, I'm probably not going to take it tomorrow. The bag is huge! 😀 Much bigger than I need for a couple of days. 35L is bigger than I expected. I will be taking the Minaal Daily - it's 21L and just physically much smaller.

      I'll be taking it to San Diego next week though to try it out on a longer trip.

      I've had my bag for a few days and I love it. Everything in the layout makes sense, with one very minor complaint. The bag is super comfortable to wear (I'm big and tall) and I like that I can remove the sternum straps, as I've never been successful with those. I haven't travelled with it yet, but have used it around the city.

      - I *love* the hidden pocket and the super secret hidden pocket beneath. It's a great idea and I will definitely be using it when I travel (phone in the upper one, passport in the lower one).
      - The materials are all lovely, the zips work really well, the layout made immediate sense to me. Plenty of pockets, huge space for laptop/tablet/papers. The clamshell design for packing clothes is exactly what I wanted, the compression zip works really well and it compresses beautifully making it a slim bag when needed.
      - Did I mention that I find it really comfortable? It's winter right now, so we'll see what it's like to wear fully loaded in the middle of summer, but for now it's great.
      - My biggest gripe is with the hook system on the compression strap. Under stress I find them diabolically difficult to undo (kind of like threading a needle in reverse), which could be extremely annoying in the wrong circumstances. I would've preferred the usual plastic clips most bags have. But it remains to be seen if with experience I get better at undoing them (only ever really need to undo the one on the side that opens).
      - I didn't like the way it came folded in half -- it made me paranoid that the big padding on the bag would permanently have that fold, although it seems to be disappearing after a few days.

      In summary, thanks for the loveliest bag. I'm *extremely* happy with it, it exceeded my expectations of quality, design, and practicality. Thank you very much.

      @James. Thanks for the news! Regarding the main compartment zipper, it is intentionally hidden behind the hooked flaps. As the main compartment is used the least, we keep it out of the way as much as possible. The bag also fits under the plane seat nicely, hope to hear more as we might keep this as an ongoing design project.

      @Abdul. Great to know what the bag reached Singapore so quickly! To add to your thoughts, we like to have options when it comes to pockets, so that's why there is no specific pocket for pens, as you can place them in any pocket you like. Regarding the main compartment zipper and expansion zipper, they are intentionally made that way. These zippers tend to be used the least so we wanted to minimize the clutter. Arrange them in the way that they would be hidden behind the flaps as much as possible for a cleaner look. Thanks for your input!

      Just received mine about an hour ago and had finished going through the bag thoroughly. Here are my thoughts :

      1) Was disappointed as there is no specific slot for pen(s) on the accessory pocket. However, you can just throw your pen on the zippered pocket (which I did) or over at the top of the bag, where the quick access pocket is.

      2) The compression straps looks difficult to unhook which can be a pro and con. Pro as it deters or delay potential theft. However, it can also delay you if you are rushing to grab something and are chasing time.

      What I did was the following : I would use only one side of the compression strap (ie the left side) when I want to open the bag and leave the right side hooked (which I felt the hook is redundant in the first place). Pull the adjustable straps of the left hook before you dislodge the end of the hook away. This makes things smoother in my opinion.

      When zipping up the bag, I would place the zippers of the main and accessory compartment on the centre or the left side of the bag. Because the expansion zipper is on the right and blocked by the (redundant) hook, it can get difficult to open the main zippers if they are on the right side of the bag as well.

      I am pleased that it came way earlier than the projected date; in fact it comes only a day after I receive my confirmation email. Kudos to that.

      I have yet to test the bag out. I am planning to bring it for a couple of short and weekend trips this month to see whether it can hold what it promises. Subsequently, this will be my only carry on backpack for extensive travels to anywhere in the world.

      Thank you Oppose This for giving me the opportunity to help design the bag and making my idea come to life. As for my fellow backers, I hope the couple of points mentioned above are helpful.

      Cheers from sunny Singapore

      I received mine in Connecticut USA. It arrived Saturday but required a signature so I had to wait until this morning to pick it up.

      First impression is that it's well built. Lots of organizational options. I really like the topmost small zippered pocket as a place to stuff my wallet & phones when I'm going through security. Just need to make sure I don't fill it with other stuff.

      Couple of issues - the compression straps use steel flat hooks that route through webbing tabs. These straddle the main D-shape zipper for the main compartment. You need to unhook them to unzip the main compartment. They're initially a bit fiddly to get in & out of the webbing tabs.

      The pear-shape was surprising and I don't understand the propose - I prefer a rectilinear shape as I tend to slide these under the seat in a plane. From an aesthetic standpoint it's an odd design choice as well. I also like the ability to hide the shoulder straps behind a panel so I can carry it like a business bag instead of a backpack.

      I currently use a Minaal Daily for trips under 3 or 4 days and a Tom Bihn Western Flyer for any trip longer than that. They're the only bags I bring - one or the other but I'm a one-bagger.

      I'll be using this one for my next couple of trips - an overnighter this week and a 4 day next week. I'll update my comments with my experiences after that as well as a couple of tweaks I'm making (to capture the excess straps for instance).

      I just received my shipping notification (blue bag) :)

      Not yet, I've got a few trips coming up in a couple of weeks - would be great to get the bag in time!

      Hi creator,

      I just got the survey for shipment. Does that mean we will be able to get the bag earlier than expected ? Thanks


    17. px 2-time creator on

      Hey Gavin! It will remain, for the most part, very similar. The layout for the pockets inside the front compartment is the only part that will be changed.

    18. Gavin on

      That review was of a pre-production unit - is the final version significantly different?

    19. px 2-time creator on

      Hey James!

      Production finishes and shipping should begin in early March. If we receive a portion of the batch before then, we will ship them on a first-come-first-serve basis. In that case we will post an update to let everyone know. :)

      Any update on production progress ? Thanks

    21. px 2-time creator on

      Hey Gavin. We don't have the final version yet for a proper picture but you can check the pocket layout prototype in this pic:…

      What changed: the sizing of all the pockets, the zipper pocket has been moved up, changed the material for more durability.

    22. Gavin on

      Gday! Any pics of the final front organization pockets?

    23. px 2-time creator on

      Hey James! The design will remain the same apart from the slight improvement to the organizational pockets in the front flap compartment (wider and differently arranged pockets).

      Just a little question, will there be any adjustment to the design of the bags ? Thanks

      A little bit of this, a little bit of that. Perfect timing - just posted an update!

      Ahh .. Thanks for the clarification. Also got the new email. Can’t wait for the bag :)

    28. px 2-time creator on

      Hey Syed,

      It works. I think the problem was the way the headline was presented in the email - made it seem you chose blue, even though you chose black :)

      Syed Raza

      Think there’s something wrong with the form. Tried opening it before and it wasn’t working. But now I’ve chosen ‘black’ twice but keep getting an email that I chose blue.

    30. Jonathan Peter on

      Thank you for the video! Looking forward to the final version of the organizational pockets :) also secretly hoping for a packing video once everything is finalized hehe

    31. Jonathan Peter on

      Thank you very much! I was hoping for there to be something like a tablet sleeve in the laptop compartment but thats alright I guess!

      Looking forward to the video :)

    32. px 2-time creator on

      In the final version, the front organizational pockets will get a slight face-lift. As of right now, the picture in the campaign shows everything pretty well.

      The laptop compartment doesn't have any additional pockets. Although, it's divided into two sections - a laptop sleeve and a space between the main compartment's wall and the sleeve itself, which you can use for a magazine or something similar.

      For the packing part, I will try to post a video before the campaign ends on Saturday!

    33. Jonathan Peter on

      Thanks! I just wanted to see how many things one could fit in the bag from start to finish, I was mostly interested in the front organizational pockets and if the laptop compartment had any additional pockets as well.


    34. px 2-time creator on

      Hey Jonathan!

      The video shows all the pockets, albeit in a quick fashion. Is there a particular one you'd like to know more about?

      No stretch goals per se. Although, if enough people sign up for the survey this Friday, we will introduce a blue version as well. :)

    35. Jonathan Peter on

      Hey guys

      Just joined in! Had a question though, can you put together a packing video of sorts that goes slowly through the various pockets and slots?

      Would be great if others can see the insides and stuff :P
      Also any possible stretch goals in sight? :)

    36. px 2-time creator on

      Hey Joshua!

      Yes, you can partially open it that way. :)

      In regards to the navy version as long as we get 30-50 people who want it - why not! I will post a survey by the end of the week to see if there's interest.

    37. Joshua Corin on

      Hey Guys,

      Is it possible to access the large main compartment from the top when the bag is standing up and the side flaps are still closed? If you didn't want to lie it down and open it up fully?

      I'd love a navy version of this is there is interest from others - perhaps a survey could be done?

    38. px 2-time creator on

      Hey James!

      Thanks for stopping by Suburban!

      We plan to leave the strap thickness as it is. Most puffy straps out there tend to be less stable and, hence, less comfortable. I know, it sounds counter intuitive, but that's our experience. That being said, if the real-world feedback we get from you guys disproves our assumption, then we will definitely look at ways to improve and reiterate the straps. But we need people to actually use it in a normal travel scenario first.

      We wanted to begin making these bags at the end of this month, but we ran into a supply delay with YKK, which postpones production till January. You will definitely get it by the promised date, but until production begins, it's hard to say when exactly.

      Hi Creator,

      I paid a visit to the suburban in Hong Kong last week and the backpack looks really good to me. You guys did a great job. And i just have two questions to ask. First, i found that the straps are still a bit too thin for me, i know that you did mentioned that the straps are already being modified. However, i think it would be better if it can be thicker to provide a more durable and comfortable for daily use, or do you have any concern to make it this way ? Second, i know it's too soon to ask, but i still wonder if we can get the backpack earlier since the design is almost finalised and i just can't wait to get the backpack. Thanks

      Hi Ken,

      We are long past the issues that the very first Invisible Backpack had. The straps on this carry-on have improved form and thickness so it shouldn't be an issue anymore.

      Hi James!

      Thanks for being a part of this.

      I previously owned the first Invisible Backpack and loved the design and quality (though the straps tad bit thin for me). Has the straps been improved since the first gen one?

      James Hatch on

      Having helped (in a small way - by commenting on choices and options during the design process) you get this to the launch stage I wanted to say that I am eagerly anticipating the release. I'm an avid one-bagger and think this is probably the best bag for that type of travel. Right now I'm alternating between a Minaal Daily and a Bihn Western Flyer. Both are similar to each other & your new one. But, you've addressed the issues I have with both of those bags! Thanks for listening to all of us who collaborated with you. Waiting for April with a lot of anticipation.

    44. px 2-time creator on

      Hey Robert! Let's tackle those questions:
      1. Short – Invisible Carry-on requires larger and longer zippers, which means we need to give them as much room as possible to work properly. The side flaps were a way to make them less noticeable.
      Long - There are three ways of hiding a zipper - (1) use a small concealable zipper, (2) hide it under some excess material, (3) place openings in a place you don't see them. The Carry-on is different from our other everyday backpacks in that it requires longer zippers and bigger zipper heads due to its construction and the way it will be used. With longer and bigger zippers comes the question of usability. If we would place concealable zippers, they would most likely break. If we place excess material to cover them up, you would curse every time you’d need to access a bigger compartment. Placing zippers somewhere you don’t see them might be an option. But if you want separate and quick access to, for example, your laptop, it limits our options greatly. The side flaps came from this very problem of having zippers mess with the aesthetics of the bag. They don’t cover them up completely, but do create a much more fluid object.
      2. They’re perfectly fine for normal use. Reversed zippers are just like waterproof zippers without the coating. And yes, I know the coating part sounds important, but you will notice the benefits (easier pulling) much more than the drawback (less water resistance). To be honest, there are more important aspects to water resistance than zippers (like the main material, construction, and conditions).
      3. The inner liner you see in the picture is a treated grey/blue polyester material. The same we currently use in all our bags.
      4. The back was changed to provide more padding and more structure. It is divided into two sections with a flexible plastic part in the middle. Don’t worry, you won’t feel it.

      Robert Tomas Vince on

      Hi all,

      It looks like a great bag! I have always been interested in your work and your bags so I am excited for this project. I read the posts on the Project: Carry-On from your website and the research and different categories. I had a few questions.

      - Your other bags have had great was of hiding the zippers and zipper path and having a clean "invisible" or (ability to hide these pockets and things). The Carry On has a great clean front and back look, but there are so many zippers and zipper paths (for the laptop, main, expandable, front) it just seems like a lot to look at on the sides. Were there any other considerations for all these zipper paths or just that it still has that clean look? Is there another way to hide the zipper paths or covers? Can only the zippers from the main compartment hide behind the external strap? Is there another way to hide or block the zippers?

      - You mentioned in the previous comment that they are non-waterproof reversed YKK zippers instead of weatherproof. How do these zippers and zipper paths keep from water penetration? With it being most of the bag on 3 sides.

      -What is the material inside the front access pocket for pens and notebooks storage made out of? The grayish colored material

      - How is the back paneling system or padding different than your other invisible backpacks? I noticed it had two vertical padding.

      Thank you for your time!

    46. px 2-time creator on

      Hey Onno!

      Good questions!

      1. No bottle holder. Due to the expandable nature of the bag we couldn’t add a separate pocket. Options? Well, the front compartment is deep and a quick way to store and access your bottle.
      2. Lockable? Yes and no. The zippers themselves don't have this option. But if you have a lock, you can use it on the zipper pullers.
      3. Passport pocket is not RFID protected. But you can store an RFID protected wallet there if you choose to.
      4. No dedicated cable routing hole. But for battery emergencies, you can store the battery in the front compartment and just pull the cable to the front. Not as glamorous, but it does the job. :)
      5. Expanded - 33L
      6. They are non-waterproof reversed YKK zippers. Weatherproof zippers are harder to pull on. They work fine on smaller backpacks, but when a bag is bigger and requires longer zippers, it can get annoying and uncomfortable. Rain is not a problem to the ones we use, but I will agree, they don’t look as cool. �

      I think that’s everything. I will add an FAQ section to the campaign. If anyone thinks of any other questions we should add, let us know!

    47. Onno Krause-Leipoldt

      Two more questions:
      How many liters can the bag hold when expanded (couldn’t find that in the info text and
      Are the zippers YKK and water proof?

    48. Onno Krause-Leipoldt

      Is the passport pocket rfid protected?
      Is there some kind of cable routing hole so I can keep a powerbank inside the bag but charge my phone whilst I walk?

      Sorry for all the questions, but I have bought and tried so many onebagtravelbags and I still have not found the perfect one for me!
