Production & Design Notes: Cambiata

TOM BIHN Crew discuss Aubergine Cambiata tote backpack

What follows is a summary of production and design notes pulled from various meetings, our project management app, and our recollections. Folks appreciated our Techonaut Pre-Production Batch and Le Petit Derriere Pre-Production Batch notes that helped explain more about design choices and considerations, as well as the manufacturing process. We first experimented with this format for the Old School Carry-All; see our Production & Design notes: OSCA edition. Now it’s the Cambiata’s turn.

We share these notes in the hopes they give you a sense of what it’s like to be here on the factory floor and understand more about what goes into realizing the design of a pack like the Cambiata.

The origins of the Cambiata are pretty interesting. The concept originated in the forum where some customers shared their desire for a tote/backpack hybrid with a few key features. With this in mind, we set out to create the first sample back in late 2021.

A lot of desired features went into the first sample: A bag that stands on its own, shoulder straps that can be stowed away, a separate laptop compartment for ease of access and quick access pockets for the essentials.

There was a lot we went back and forth on: The tote straps – grab handles or over-the-shoulder straps, the removability of said straps, and how much internal organization we wanted to include.

Additionally, we wanted to make backpack straps that could be folded and neatly stored in the back pocket. With this goal in mind, we used the same backpack straps as the Zeitgeist and Paradigm which folded nicely into the back compartment with an additional bartack to allow it to lay straight, which Mike thought was really clever.

The first version of this bag was somewhat similar to the current edition but needed some key changes before it would truly transform into the Cambiata.

Our first attempt had two short grab handles with Poron foam, much like some of our existing totes. Even with the cushiness of the Poron, we found these short grab handles to be uncomfortable for a bag with this carrying capacity. 

We wanted the bag to hold a lot, in particular large laptops, and took inspiration from the Techonaut when creating the separate laptop compartment. The original version was even bigger if you can envision it. We decided to size the bag down to a more comfortable tote size, but found that the short grab handles still were not the most comfortable for carrying. We considered perhaps sizing the bag down even more, but the piping that enables that bag to stand on its own, combined with the location of the zipper for the exterior laptop compartment, was already presenting the bag as a (fun!) challenge for the joiners on the floor. A smaller version would likely require a new design that excludes the separate laptop compartment.  So we went back to the drawing board.

Our second iteration of the Cambiata had longer tote straps, allowing it to be worn over the shoulder. While this solved our handles problem it left us with another issue: Finding the perfect length. We tested the bag on crew members of varying heights and got their feedback. 

 As we attempted the search for strap length we found ourselves with another consideration – due to the U-shaped opening and the location of the backpack straps, the tote straps would not “kiss” perfectly in the middle of the bag. To counteract this we thought of narrowing the bucket compartment opening by 1" (1/2" on each side), lowering front seams to line up with back seams, and attaching the handles.

Mike was quick to point out that by lowering the front seams we would be creating a stress point to the small joining seam at the zipper on both sides of the bag, due to the webbing strap pulling on the seam allowance where it was currently attached. This left the bag in an interesting position, as the stress created from this seam would prove the main zipped compartment hard to open when the handles were in use. 

It was suggested that the zipper opening be narrowed to curb the issue, but by changing this element we would be affecting multiple pattern pieces and eventually create a problematic production process for the team. So with this in mind, the team went back to the drawing board to assess how to handle the tote straps of the Cambiata.

Production Manager Fong proposed the solution of one strap and it seemed to be the perfect solution to all of our problems. It could be completely adjustable for any height, is comfortable, and could even be removed for those who preferred the Cambiata as a backpack only. 

When Fong’s idea was added to the bag, we found it was the perfect solution for the bag. With the adjustable shoulder strap, the bag was not only able to function as a tote but as a messenger bag as well!

Some fun details on our color choices – we loved the playful look of the Zest against the Black as well as the understated Mountain Grey against various exteriors. We decided to mix things up with the blackout label, pairing it with our Deep Blue exterior for the first time. 

After finalizing our design, we did a bag demo for the broader crew (which we featured on our Instagram stories!) and the feedback was very positive. The bag looks very different from many of the bags we have in the line and we see it as a welcome change!

I agree with Gary. The lack of D rings for my own straps is what’s preventing me from buying this bag. Reason being, if the bag had D rings, I could actually attach it to my stroller hooks and use it as a baby bag! It’s perfect as a baby bag because it has a bottle compartment that looks pretty insulated, and the laptop compartment can be used for diapers and wipes, and the u shape makes it easy to see everything inside at once.

Hi Heidi! We have an accessory in the works that will allow for the attachment of the D ring :)

Great to read the insights into the design process – looking forward to hearing about the new D-ring hack!

Looking forward to sharing it!

Very interesting to read. I can’t wait for its arrival. I am going to use as my daily carry backpack mode only. I ordered black and very excited for interior color. I have this syndrome like many Bihnions – cannot wait until it arrives but it’s worth the wait. I appreciate all the products and information the team put it out there. Cambiata looks like another awesome product :)

We can’t wait for you to get it! The Black / Zest is stunning in real life!

Nice article. Why did you use only use fabric loops so that make it hard to use our own carrying straps? Like the Tom Bihn Absolute Shoulder Strap? There are simple workarounds and hacks one can use to get around this, but why make this bag so shoulder strap unfriendly out the starting gate?

Hi Gary! Thanks for taking the time to drop us a note, that’s a great question. During the design process, we did talk about potentially attaching d-rings since some folks could be interested in alternate straps. The overwhelming feedback we received was that the bag would lose its clean look when the shoulder strap was taken off — you’d have the d-rings flopping around at the point of entry on the bag and that wouldn’t look great. Also, many have expressed that they preferred the bag solely in backpack mode and didn’t have too many preferences for the other carry methods. That said, for those who do want to use an Absolute Shoulder Strap (or any of our other straps), we’ve designed a potential accessory with a D-ring that can be attached onto the fabric loops! More info to come soon…
