Expanded: 40x51x24 cm when full (Excluding the straps).



Added 3 More Mesh Pockets to the main outer compartment


Improved strap materials for increased comfort and durability


The GRANDE features a built-in charging station through the MOS Reach+ and MOS REACH C with an internal cable management so you can charge everything without taking it all out of your backpack.


With built-in cable management, you'll be able to keep everything organized and within easy reach. The Orange lining is also used to make every item and cable easy to see even when things start getting packed.


We designed the GRANDE with the idea in mind that you would be taking everything with you. The straps are wide to fit any shoulders with a comfortable backing that allows ventilation when everything is weighing down on your back.


The GRANDE is stylish and professional enough to take with you to the office, but rugged enough to take with you the next time you trek across the globe.

It's great!

I never thought I'd "get into" a backpack. I originally ordered the smaller version, which was amazing, but was lacking some space for my needs. The larger version is great when I need to carry multiple laptops, a tablet, and a lot more stuff.

Legendary backpack

I love the expanding pockets, the cable passthrough, and the ability to run a battery bank and a power strip from the backpack. I have it set up to charge my iPhone and iPad when in the backpack (iPad Pro 12" is too big for the tablet pocket but the laptop pocket holds two laptops and my iPad). I'm going to use the water bottle pocket for my G-Fuel to get work done with my water bottle. (Shame it doesn't hold the 40 oz. bottle) And, I've got plenty of room for small miscellaneous tools such as bootable flash drives, USB adapters, and so on for easy access instead of digging through my 3 cu. ft. tool bin. The flat open pockets, bright orange interior, and expanding pockets make it totally awesome.


I was struggling to fit all my computer gear in my old backpack but this one fits it all and I still have pockets empty!!!

It knew it was big. It was bigger than i thought.

The capacity of this backpack is incredible. I use it for college and, when extended, it can carry my laptop, notebook/binder, accordion folder, a pretty large 8 Qt plastic box with dimensions (12.48 x 4.45 x 8.66)in, another medium sized plastic box with dimensions (10.8 x 7 x 1.7)in, another small pencil box, some tools and school supplies AND i could still fit even more stuff thanks to the sheer capacity and amout of bags provided. (I still haven't even used one of the zipper bags haha)

Though, i should mention that while all of that fits, it makes it look a little uncomfortably full. However, it is also a lot more space that most people would use. I don't even need that much space, i just don't have more efficient boxes, so theres a lot of dead space. Also, it's just that i feel uncomfortable. I am absolutely sure that the quality of the materials can take that load. So basically, theres a looooooot of room.

It's big, it's pretty sturdy and super useful thanks to its charging capacity. Just be careful that if you do use its full extended capacity at maximum, you will be like 3 times bigger from front to back, lol.

Stays slim but tooooooo wide

So wide that I cannot move my arms back and forth. Possibly good for a (very) large adult man. Generally, I would say that its generally way to wide for the general population of healthy non-obese ppl

We're sorry that backpack was too big! The Grande is our largest backpack, please reach out to customer service if you would like to send it back and order a different style that isn't as large as the backpack.
