This €199 COS bag keeps selling out for the 2026 back-to-school season
Finding a bag that is elegant, roomy, and able to fit a laptop is a challenge many people know all too well as the new season approaches. The COS bag Trullo has clearly found the answer, so much so that it has been selling out repeatedly since the start of the 2026 back-to-school season.
A format designed for everyday office life
What sets the Trullo apart first and foremost is its generous width. It comfortably fits a laptop alongside everything else you need for a busy day. For anyone looking for a bag that can keep up with a professional pace without compromising on style, that alone is a compelling argument.
Its slouchy silhouette, slightly relaxed and unstructured, stands in sharp contrast to the rigid, boxy styles we know so well. This softer shape speaks to a strong appetite in the fashion world for accessories rooted in real, everyday use, far removed from anything too formal. The result is a bag that adapts to what you put in it, rather than the other way around.
On price, the Trullo comes in at €199. That positioning, combined with its design, goes a long way towards explaining the enthusiasm it has generated since the 2026 back-to-school season.
The COS Trullo bag and the quiet luxury aesthetic
The Trullo’s success is not purely down to practicality. Its design sits squarely within the quiet luxury movement, the trend that favours clean lines, minimalist silhouettes, and understated colours. It is a look that fashion lovers simply cannot let go of, and one that COS executes with precision.
This aesthetic positioning gives the bag a rare versatility. It moves effortlessly from the office to other settings without ever feeling out of place. That is also what makes it a back-to-school essential rather than just another seasonal accessory.
Demand has been so strong that the COS e-shop regularly shows the style as out of stock. A restock is expected soon, according to notifications on the site.
The Soft Flap Bag, COS’s answer to the craze
Off the back of the Trullo’s success, COS’s creative teams have been working on a new style. The Soft Flap Bag takes the same aesthetic codes as the Trullo but offers an even more generous format, ideal for anyone who wanted just a little more room for their daily essentials.
This new COS bag also stands out for its double-handle design. A short top handle lets you carry it by hand, while a second, longer shoulder strap offers a practical alternative depending on the moment. That flexibility is a genuine asset for a bag meant to carry you through an entire day.
It is available in two colourways. Classic black delivers maximum versatility, while burgundy slots perfectly into the autumnal tones that are highly sought-after this season. It is priced at €249.

Two bags, one COS philosophy
With the Trullo and the Soft Flap Bag, COS offers two takes on the same vision. On one side, an already cult style that is nearly impossible to find in stock. On the other, an amplified version that meets the same expectations with even more space and a dual-handle design.
For the 2026 back-to-school season, both styles embody what so many people are looking for in an office bag: a clean, elegant design, genuine carrying capacity, and the kind of everyday adaptability that actually matters. The COS bag Trullo remains the one to watch the moment it comes back in stock, because it is very likely to sell out just as fast as it did before.
