Since our release of the MOS Blackpack last year we’ve been working to make the best Large Travel backpack for your Electronics – One that can stand up to the rigors of almost any adventure and that you can plug in to charge all of your gear, and hold even more stuff than our last backpack... The MOS Blackpack Grande is the next step in our quest to make the best tech travel bags in the world.
The Pack does not include a MOS Reach C. It is available for purchase separately here.

Dimensions
Unexpanded: 52 cm by 52 cm by 18 cm when full (Excluding the straps)
Expanded: 52 cm by 52 cm by 24 cm.
The Blackpack Grande is a combination of our MOS Pack Grande and our MOS Blackpack (Surprise). It holds a lot of stuff and is made out of high-end materials so it should last you a long time, and of course, it has all of the features people have come to expect from our backpacks.

It’s our second one we’ve purchased. The first is several years old and still looks brand new. It’s a great college backpack and did a great job while
Traveling in Italy.
I bought the Original Blackpack a few years ago,and have been completely satisfied with the product. With the one exception, that I am a Big Guy! At 270 lbs. and 6'1',I needed more room for my "Oversized" life! The new Blackpack Grande is exactly what I needed! Thank You for thinking about the "Larger than Life" Crowd! :)
I am very pleased with this product, and best of all it fits a 17.3" laptop just like it said it would.
The webbing takes some getting used to, but does it's job of holding things in place. I also like all the number of pockets.
Had the bag for a couple of weeks, just before I went on the road, and it’s serving my needs perfectly. When you have all the electronics (gaming laptop, accessories, iPad, kindle, and a switch,) it fits all of it comfortably. I love being able to plug the backpack directly to the wall to keep everything ready to go.
I already have the MOS Backpack v4.0, but it is too small, you put a 15' laptop some cable but it is complicated to put in it more.
So I bought the Grande which is the best way to carry all the needed elements to use my professional laptop.
One point as minus = the customer service. You will receive your bag with a label containing a QR code to see a presentation all the features of your bag... but it tries to launch a webpage on the MOS website, and this page does not exist anymore.
So Sewell, please just remove this label, it is anticlimatic to want to discover all the features of a product turned to high tech tools, just to discover a error 404 . Or to give the best service, find back this presentation and activate it again.
