The verdict, explained

At 21.75x14.5x11", the Patagonia Black Hole Wheeled Duffel 40L exceeds Brussels Airlines's 21.6x15.7x9.0" carry-on sizer — it is 0.1" too big on its longest side, 2.0" too big on its shortest side. Even with the straps pulled tight, the overage is too large to count on squeezing it in. Expect it to be turned away at the gate and gate-checked. On Brussels Airlines: Light fare includes a small item only. It is too large for Brussels Airlines's under-seat personal-item space, so it has to go overhead or be checked.

💡 At the gate

Airlines measure at the widest external point — wheels, handles, and bulging pockets all count. Pull soft-bag compression straps fully tight before you size it.
