The newest edition to Patagonia’s line of packs and luggage, the MLC Bag is a burly, soft-sided 45L convertible backpack suitcase with enough room and compartments for all kinds of travel.
Regardless of where I’m going or the duration of my travels, I try to always pack everything into a carry-on bag. Paying for checked bags is not my jam, and if you have everything with you, you can avoid waiting in baggage claim or items potentially getting lost in transit. Patagonia’s Black Hole line of bags and duffels has long been a go-to option for adventurers for years. But the newest in the Black Hole collection is the MLC Pack.
In short: The MLC is designed to keep you organized while on the move. This isn’t your standard, one-compartment duffel — it includes a variety of different internal compartments for storing your laptop and other essentials, and at 45 L, it meets most carry-on requirements. With three different carrying configurations, it’s also versatile enough for many types of travel.

Multiple Ways to Travel

The MLC Bag (which stands for Maximum Legal Carry-on) is designed to allow you to travel any way you like. Three carrying configurations allow you to carry the bag as a backpack, shoulder bag, or duffel, or you can stow all the straps and simply carry the bag by the center handle.
My Take: Pros and Cons
I have always loved Patagonia due to its commitment to the planet and the fact that they make functional, durable, and well-made products. So, I fully expected to like this bag. But, it turned out that there were things that I both liked and disliked about this pack.
The fact that it converts from a suitcase to a backpack is my favorite feature, as hauling a heavy duffel bag around can be a challenge. The option to easily convert over to a backpack makes long walks through the airport or to bus stations a lot more comfortable, especially with the padded back panel and shoulder strap.
