PORT Chicago EVO — A Real Wheeled Trolley That Becomes a Backpack
2-in-1 Trolley and BackpackOwn Wheels + Aluminium Handle15.6" Laptop · 25 LIATA Cabin Format
This is a genuine wheeled trolley with its own wheels and its own telescopic handle — not a backpack with a sleeve for someone else’s suitcase. PORT Designs files the Chicago EVO under Trolleys and calls it, in French, literally a backpack on wheels. Roll it on its quiet wheel system with the aluminium telescopic arm extended; when you need to carry it, the arm stows in its own dedicated pocket and the padded backpack straps come out of a rear pocket. It holds 25 litres in a 320 x 200 x 535 mm body weighing 2.52 kg, with a padded notebook compartment of 260 x 35 x 385 mm for a 15.6 inch laptop, a padded tablet compartment for devices up to 10 inches, a large main compartment for clothing and a front organiser. A protective bar at the base guards against knocks, and PORT states the format is IATA-compliant for cabin travel.
Compatibility — check before buying:
Be precise about what this is, because PORT sells two different Chicago EVO products. There is a Chicago EVO Backpack with no wheels at all, and this, the Chicago EVO Trolley and Backpack, which has both. Several catalogues shorten this one to “Chicago EVO Backpack”, which will send you the wrong product class. Equally, calling it purely a trolley hides the backpack function. It is a 2-in-1: wheels and an aluminium telescopic arm, plus stowable backpack straps.
It weighs 2.52 kg empty. That is the price of carrying a wheel-and-handle assembly on your back when you switch modes, and it is worth knowing before you buy — a comparable 25 litre backpack would be roughly a kilo lighter.
PORT does not publish a wheel count or wheel type, only a quiet wheel system, so we state neither. It also publishes no water-resistance claim and no rain cover, and no recycled content: this is the standard Chicago EVO, not the ECO line. PORT runs a separate ECO Chicago EVO Expandable backpack — do not carry its recycled claims onto this part number.
On the IATA reference: PORT states the format is IATA-compliant for cabin travel. Airline allowances differ from the IATA guideline and several carriers have reduced theirs, so check 320 x 200 x 535 mm against your airline’s current limit rather than relying on the category.
Material: PORT publishes “polyester”. The 1680D figure that appears on some listings is distributor detail rather than a PORT specification.
Best For
✓ Business trips where you roll through the airport and then carry the bag up stairs or over cobbles
✓ Anyone who does not want to own both a cabin trolley and a laptop backpack
✓ Carrying a 15.6 inch laptop, a tablet and an overnight change in one 25 litre bag
✓ Commuters with a heavy daily load who would rather wheel it most of the way
✓ Travellers who want the trolley arm out of sight — it has its own dedicated storage pocket
Key Features
Genuinely 2-in-1, not a trolley sleeve
The distinction matters. Many backpacks have a fabric band that slides over someone else’s suitcase handle. This has its own wheels and its own aluminium telescopic arm, and separately has padded backpack straps that stow in a rear pocket. You are buying one bag that does both jobs, not one that borrows another bag’s wheels.
An aluminium arm with its own pocket
The telescopic handle is aluminium, and PORT gives it a dedicated storage pocket so it is out of the way in backpack mode rather than digging into your back. Small detail; it is the one that decides whether a convertible is actually usable in both modes.
Quiet wheels and a protective base bar
PORT specifies a quiet wheel system, and a protective bar across the base to take knocks — kerbs, steps and the boot of a car are what wear out a wheeled bag first.
25 litres, properly divided
A padded notebook compartment of 260 x 35 x 385 mm for a 15.6 inch machine, a padded tablet compartment for devices up to 10 inches, a large main compartment for clothing and personal items, and a front organiser. Enough for a laptop, a tablet and an overnight change.
Padded backpack straps that disappear
The shoulder straps stow into a rear pocket, so in trolley mode there is nothing flapping or catching. Reinforced padded carrying handles cover the short lifts.
Two-year manufacturer warranty
PORT publishes a two-year warranty covering accessories and trolleys, with repair or replacement for defects, and states explicitly that it does not affect your rights under the law.

Frequently Asked Questions
Is it a backpack or a trolley?
Both, genuinely. It has its own wheels and its own aluminium telescopic handle, and padded backpack straps that stow in a rear pocket when you want to roll it. This is not a backpack with a sleeve for someone else’s suitcase handle — PORT files it under Trolleys and its French name translates literally as a backpack on wheels.
How many wheels does it have?
PORT does not publish a wheel count or wheel type for this model, only a quiet wheel system, so we do not state one.
What does it weigh?
2.52 kg empty. That is the wheels, the aluminium arm and the base bar. A wheel-less 25 litre backpack would be around a kilo lighter, so if you will mostly carry rather than roll, consider PORT’s Chicago EVO Backpack instead.
Will it go in the cabin?
PORT states the format is IATA-compliant. The bag measures 320 x 200 x 535 mm. Airline allowances differ from the IATA guideline and several carriers have reduced theirs, so check those figures against your airline before travelling.
Is it made from recycled material?
Not this one. PORT publishes no recycled content for the standard Chicago EVO. PORT does sell an ECO Chicago EVO Expandable backpack with its own claims — those do not apply to this part number.
Is it water resistant?
PORT publishes no water-resistance claim and includes no rain cover, so we make no claim either.
What warranty applies?
PORT publishes a two-year warranty for accessories and trolleys, with repair or replacement, and states it does not affect your statutory rights. Note that PORT’s advertised 10-year term covers its PORT Connect docking range, not bags. Our store warranty is one year, alongside your statutory rights.
Singular Expert Insight
Convertible trolley-backpacks have a bad reputation, largely earned by products that do one job properly and the other badly. The Chicago EVO avoids the usual failure in a specific way: the aluminium telescopic arm has its own dedicated storage pocket. That sounds like a footnote, and it is actually the whole thing. The reason most convertibles are unpleasant to wear is that the handle assembly sits between the straps and your spine. Give it somewhere to go and the bag becomes a bag.
The case for the format is simple and, if it applies to you, unanswerable: airports are flat and everything after them is not. Wheels are effortless on a concourse and useless on a staircase, a kerb, or the cobbled street between the taxi rank and the hotel. If your trips reliably contain both, owning one bag that switches beats owning two.
The cost is 2.52 kg empty. There is no way around it — wheels, an aluminium arm and a base protection bar weigh what they weigh, and you carry all of it on your shoulders in backpack mode. If nine journeys in ten are a walk to an office, this is the wrong bag and PORT’s wheel-less Chicago EVO Backpack is the right one. That naming similarity is, incidentally, the single biggest ordering risk on this product: PORT sells both, several catalogues shorten this one to “Chicago EVO Backpack”, and the two are entirely different things.
Inside, 25 litres is divided sensibly rather than generously pocketed: a padded 15.6 inch notebook compartment, a padded tablet pocket for 10 inch devices, a large main compartment for clothes, and a front organiser. That is a one-night trip with a working laptop, which is exactly what the format is for.
What PORT does not tell you is worth listing, because several retailers fill the gaps confidently. No wheel count or wheel type — only a quiet wheel system. No water-resistance claim of any kind, and no rain cover. No recycled content: this is the standard Chicago EVO and PORT’s ECO line is separate, so any sustainability claim you see against this reference has come from the wrong product. And PORT publishes “polyester” without a denier; the 1680D figure circulating is a distributor addition.
The two-year warranty is real and explicitly stated for accessories and trolleys, with repair or replacement. Note that PORT advertises ten years on much of its PORT Connect docking range — that is a different product family and does not apply here.
Buyer’s Guide
Buy it if
Buy the Chicago EVO Trolley and Backpack if your journeys mix rolling and carrying and you would rather not own two bags. Go in knowing it weighs 2.52 kg empty, that PORT publishes no water-resistance claim, and that the near-identical Chicago EVO Backpack is a different, wheel-less product. Check 320 x 200 x 535 mm against your airline’s cabin allowance before travelling.
Skip it if
You want the lightest bag possible — 2.52 kg empty is the cost of the wheels and handle. Also skip it if you need a published water-resistance claim, a rain cover, recycled content, or a confirmed wheel count, none of which PORT publishes. If you only ever carry, PORT’s wheel-less Chicago EVO Backpack is the lighter choice.
Also consider
PORT’s Chicago EVO Backpack 15.6" is the wheel-less version — the same family, considerably lighter, and the product most often confused with this one. The ECO Chicago EVO Expandable backpack is PORT’s recycled-line equivalent in 15.6 and 16 inch. PORT also makes the HANOI II Trolley and the Yosemite Eco 25 L trolley if you want wheels without the backpack conversion. Browse the full range of laptop cases and bags, or see our laptops.
