19 Inch Laptop Backpack with USB Charging Port - Large 50L Waterproof Travel Backpack for Men & Women - Perfect for Business, College, Commuting & Airplane Carry-On

I've had this backpack for over a year, and I genuinely have no complaints about it. My large 17" laptop and its massive power brick fit very well along with everything else I could possibly need for work/school. The zippers are sturdy and smooth. I don't think I've ever had them snag, and well after a year of use, the zippers are smooth enough to be opened one-handed. Here are my favorite features listed;- Plenty of storage/space/pockets.- Zippers are excellent, sturdy, and smooth.- Nifty sunglasses holder on the shoulder strap- Drink slot on both sides (many backpacks only have one)- Subtle, but quality overall aesthetic, the branding is small and doesn't cheapen the look like others- Straps for comfort and support, on either side of the backpack to help keep it closer to your back and can be adjusted- Comfortable back and shoulder paddingI really can't think of any significant critiques of this backpack. I needed to buy it as it was one of the only ones that would fit my 17" laptop, but after having used it for over a year, I'd recommend it for anyone with any size laptop.
