## Our verdict

### Reasons to buy

-   A highly versatile travel bag as you can use this as a backpack, messenger bag, or a duffle bag.
-   User-friendly and straightforward to use. It can be easily integrated into your travel plans.
-   Has a clamshell opening which makes organizing your bag quicker and easier as you have full access to the main compartment.
-   The pack's stowable straps make the whole thing dangle-free and compact. This makes it easier to store in tight spaces such as overhead cabins or under your airplane seat.

### Things to consider

-   Not the most comfortable backpack for long trips.
-   Has no structure which means it has a tendency to sag when not fully packed.

## What reviewers said

-   "Love the size and weight of this bag. Super light, holds a ton, and fits into an overhead bin. Even better, I messed up on the timing of my shipment. Customer service went above and beyond to make sure I got it before my trip, after the fact, even though it was totally my fault. Super impressed with the quality and service of Patagonia."
-   "Now I have three pieces of the luggage set. This MLC in the 45L is awesome. I have a black hole duffle, and a brief case, and use these pieces regularly. They organize my life, are tough, they perform, and are just "sexy" to tote around."
-   "Absolutely incredible bag that has so many pockets for storage and opens like a suitcase. I prefer this over a duffel bag which is difficult to rummage through and find items. Great design. Easy to clean."
-   "Designed to be a carry-on size backpack and duffle and wow, does it live up to those expectations. Great for flying. Combines laptop/tablet, briefcase functions into separate compartments while having a ton of room. Absolutely recommend."

## Reviews from around the web

**Patagonia Black Hole MLC Review**
[www.outdoorgearlab.com](https://www.outdoorgearlab.com/reviews/travel/travel-backpack/patagonia-black-hole-mlc)

> Patagonia continues to impress us. They took an already award-winning travel backpack and improved its durability with their Black Hole fabric, the same stuff used on their impressive expedition duffels and backpacks...The convertible nature of the Patagonia Black Hole MLC allows for the user to carry it as a backpack or a briefcase, making this a great choice for anything from airport travel to car camping trips.

**Patagonia Black Hole MLC Review**
[www.gearhacker.com](https://www.gearhacker.com/patagonia-black-hole-mlc-review/)

> There are some good organizational pockets along the outside of the pack, and the internal organization is quite innovative as well....The ability to overstuff it, though, earned the Patagonia Black Hole MLC the Best One Bag Travel Backpack for Overpackers.

**Patagonia Black Hole MLC 45L Pack Review**
[alwayswander.info](https://alwayswander.info/patagonia-black-hole-mlc-review)

> For a travel pack that has a ton of features, great build quality, and can be that city travel pack or the outdoorsy companion you need, this is a great pick. Even more so if you are a loyalist to this brand. That said, if you're looking to an urban style, minimalist look, etc. - this won't be the droid you're looking for. With a view to its general performance, and as a long-time user of this bag, I can 100% recommend the Black Hole MLC 45L from Patagonia.
