This backpack is hands down my favorite tech bag. It's got so many pockets and it's spacious. It fits my Dell 7577 which is a THICC 15.6"laptop with an Amazon Basics sleeve on it. It's travel compartment on the back is solid and will not move on your luggage.
Very spacious, lots of pockets, and if you get the gray color on clearance, you save $30.
Here's my three gripes:
1) The backpack is not waterproof or water resistant. You can fix that by buying a rain fly on Amazon.
2)This thing is pocket galore. That being said, this thing has a lot of zippers. When you try to close a zipper, a zipper pull is dangling and gets in the way. You can avoid this by moving the other zipper pulls with your other hand, but it still can get in the way.
3) The price. Now for a tech backpack, you can honestly find something at a lower price, that's water resistant and can fit up to a 17" laptop on Amazon. Wondering why I got this one? Everyone wants a black backpack, it goes with everything. The thing is, this one was on clearance for $65. Is it worth that price? Maybe. As a rewards member, I bought this with those rewards and not my own money. I don't think it's worth the retail price. That being said, wait for this to go on sale/clearance.
