Patagonia · Black Hole Mini MLC 30L
Black Hole Mini MLC 30L: the Patagonia cabin backpack for 55 cm size limits, from the morning flight to two nights away.
The Black Hole Mini MLC 30L is a 30-litre Patagonia cabin backpack: the compact version of the MLC 45L, designed for the airlines that are strictest about cabin size. Thursday evening, the 15-inch laptop in its lay-flat compartment, two nights of clothes on the other side, the water bottle in its outside pocket; Monday morning, straps tucked away, it heads back to the office like a briefcase.

The morning flight, two nights away, home without waiting at the carousel.

Black Hole Micro MLC 22L

This bag

Black Hole MLC 45L
45 L · 1,635 g · 56 × 37 × 19 cm
For the long trip. 1 cm too tall for 55 cm limits; it fits on easyJet.
See the Black Hole MLC 45LPhotos to the same scale: 46, 51 and 56 cm tall.
In the cabin
The overhead locker, from Ryanair to Air France.
Designed for the airlines that are strictest about cabin size, it fits all six size limits we checked: Ryanair, easyJet, Air France, Transavia, Vueling and Lufthansa. Soft-sided, it squashes into the locker; stuffed to bursting, it bulges.
Under the seat
Personal item, free on most flights.
Overhead locker
The cabin bag, above the seats.
In the hold
Too big for the cabin.
Dimensions 51 × 30.5 × 18 cmMost common limit in Europe 55 × 35 × 25 cm: it fits, with 4 cm to spare in height
It doesn't slide under the seat: at 51 cm tall, it's bigger than the free bags (40 × 30 × 20 cm on Ryanair, 45 × 36 × 20 cm on easyJet). On low-cost airlines, budget for the cabin bag option.
Size limits checked in October 2026; every airline sets and changes its own rules, so check yours before you fly.




Colours
Pale khaki, black, slate blue or caramel.
Weathered Stone
A pale khaki, almost sage: against a dark jumper, you spot it at a glance in the locker.
Black
Matt black, discreet grey logo: it goes from station platform to meeting room without drawing attention.
Smolder Blue
A very dark slate blue: from a distance it passes for black, up close it has more depth.
Cinnamon Brown
A golden caramel with an orange logo: easy to spot from far off in a station concourse.
Laptop
The laptop, in a compartment that opens flat.
The padded laptop compartment opens out and lies flat in the security tray, with room for papers and cables.
15-inch
Takes most laptops with a 15-inch screen.

Ways to carry
On your back, on your shoulder, in your hand, or on your suitcase.

The fabric
The Black Hole fabric, in travel form.
- 100% recycled polyester ripstop, laminated with a recycled TPU film (a flexible plastic) that makes it weather-resistant. The Black Hole duffels go up to 900 denier.
- Lining and harness. PU-coated recycled polyester, and recycled airmesh for the shoulder straps and hip belt, all bluesign® certified.
- Factory. In Vietnam, in a Fair Trade Certified™ factory.
In the rain
A shower on the way to the airport: the laminated fabric holds.
Light rain
Water-repellent fabric
PU coating and a durable water repellent (DWR) finish: water beads up, then eventually gets through at the seams and zips.
Shower
Laminated fabric
Fabric covered with a TPU film (a flexible plastic) that stands up to the weather. The seams aren't taped.
This bag
Proper rain
Rain cover
A removable cover goes over the whole bag. Without it, the coated fabric eventually lets water through.
The seams aren't taped: in a thunderstorm, get it under cover.

Eiken's take
- Why we chose it
- Everything that makes the MLC (lay-flat laptop, a harness that disappears, a hip belt that becomes a shoulder strap) in a size that fits where the 45L is too big.
- Worth knowing
- It doesn't go under the seat: at 51 cm tall, it's an overhead locker bag, often an extra on low-cost airlines.
- Who it's for
- Anyone away for two or three nights with a single bag, on airlines that measure everything, who takes it back to the office on Monday.

Questions
What are the dimensions and weight of the Mini MLC 30L?
51 × 30.5 × 18 cm (height × width × depth) and 1,290 g empty, for 30 litres.
Is the Mini MLC 30L waterproof?
It handles a shower without being waterproof: the fabric is laminated with a TPU film, but the seams aren't taped. In a thunderstorm, get it under cover.
Does the Mini MLC 30L fit in the cabin on easyJet, Ryanair or Air France?
Yes, as a cabin bag on all three: 51 × 30.5 × 18 cm fits within 55 × 40 × 20 cm on Ryanair (Priority), 56 × 45 × 25 cm on easyJet (paid option) and 55 × 35 × 25 cm on Air France. Not as the free under-seat bag (40 × 30 × 20 cm on Ryanair, 45 × 36 × 20 cm on easyJet): no MLC fits there. Check with your airline.
Does the Mini MLC 30L have a water bottle pocket?
Yes, a stretch mesh outside pocket, made for bottles of several sizes: that's what the MLC 45L lacks, as it packs everything inside, though it takes 15 litres more.
