NUBILY Laptop Backpack 17 Inch Waterproof Extra Large TSA Travel Backpack Anti Theft College Business Mens Backpacks with USB Charging Port 17.3 Gaming Computer Backpack for Women Men Black 45L

It is a decent size and can put a lot in there. Just giving time to make sure it holds up before I give it a 5 star rating. I will update in a few months.

Great backpack. Very light and great compartments.

Lots of room. Sturdy straps. Good zippers. I love the multiple compartments. Lightweight for its size.

Size is great. All the pockets you need

This replaced prior carryon backpack. It’s sturdy and made from a heavier material than prior one so takes up a little more space. Lots of compartments. I haven’t been caught in the rain yet so don’t know about waterproof claim, but assume it is by the quality of material. I especially like the strap that allows it to sit on my roll on overhead luggage. Now I don’t need to put it on my back inside the airplane.

I love it.

Nice

We liked how organized the pockets and features are and how easily my high schoolers could use their bags for school and for traveling. Everything they need on them is easily stored and they love the USB attachment

For years my husband -- a choir/orchestra/band director -- has been using a soft laptop satchel with shoulder straps. Whenever we travel he brings a separate backpack and the laptop case. When he goes to work he sometimes needs a plastic bag for other stuff. He wore out the first one because he was also always putting other stuff for work in it such as cables, headphones, papers, etc. Hes really pleased with this one because he can also put his lunch bag in it, an extra shirt, two laptops, water bottle, and other gadgets for work. There are compartments and pockets of assorted sizes to keep everything separate and organized. The cherry on top is the USB port and cable so our power bank can charge his laptop or phone.

This is a quality backpack.
