Pleased with purchase
Mystery ranch makes a good product, this fits my needs and is well made, I have two of these one is a smaller version. They are comfortable for what i use it for, back and forth to work on my sport bike. Zippers are heavy duty the whole pack is well made. I would recommend this for someone that wants a smaller pack that has a laptop sleeve.

Nice pack, but slightly oversized laptops won't fit
Very well made and had plenty of storage compartments, but a 15" gaming laptop won't fit. Had to return it because of this.It would really help if Mystery Ranch would specify how wide and deep the laptop pocket is instead of just specifying that it can hold up to a 15" laptop. Not all 15" laptops are alike!

Perfect for light day to day activities or travel
The back back is smaller then it seems but still packs well not recommended for a 2-3 day trips but very durable and made with quality

Almost perfect!
I LOVE everything about this backpack. I've had it for more than two years, and it stands up to everything. That said, the four star rating is solely because I have to hand wash it, which is pretty tricky. I get in the shower and use the wand. I can't throw it in the hand wash cycle of the machine.
