I was originally attracted to Mos/Sewell because of a youtube vid about tech backpacks from 2018. The Mos Blackpack that was shown in the review had me in love the second I saw it. You cannot imagine my disappointment when I saw the redesign of the blackpack with the strange wing pockets instead of the hide-away water bottle pocket. Luckily there was this Mos Pack!!! Almost exactly like the original black pack just with a few material/color differences...and no built-in rain cover (really sad about that!!!) and then my heart broke again! No black only blue! So I hit Amazon once again paying homage to our retail overlords. Been using it for a few days and really happy. Just ordered the charging doc for it. Sad the original isn't avaliable or I would have grabbed that too.

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.

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 www.lttstore.com 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!!!

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.
