WITZMAN Canvas Travel Backpack - Convertible Carry-On for Men & Women | Perfect for Air Travel & Outdoor Adventures

You can fit a lot in this backpack. I head to the airport monthly for a 3-day flight trip with just this. I can just fit my dirty construction boots and hard hat in the bottom, where they are separate from my clean clothes, which all fit nicely in the main area with my 2 laptops, their big batteries, and an extra pair of shoes. The liner separating the main and bottom compartments is versatile, allowing more up top or on bottom. There is plenty of space in the top zipper flap for toilet articles, and my essentials I want close at hand all day fit into the roomy front and side pockets. I can fit my larger kindle in the front or top zipper pockets and not take up anywhere near the entire pocket, and it fits into the open (deep) side pockets. The fabric is very durable, and I have had no difficulty with the zippers (though the top hidden zipper pull can sometimes be hard to get at). Quality is great, straps are comfortable and very adjustable, and the bag has a cool look to it that I love. I also love all the clips and straps (great for a rolled up blanket or jacket).I even fit my pre-packed daypack and hiking shoes in there once—along with all my usuals (minus the hard hat, I think).However, it isn’t quite perfect: it’s really a 4-1/2 star bag, but I can be a picky over packer who is searching for “the perfect travel backpack”—“for me”—and this is still above its competition. The side pockets are difficult to get your fingers in and out of, especially the zipper pockets—especially if the inside of the bag is packed to its limit. More elastic fabric at the openings to these pockets would be a design improvement—but as they are, you don’t have to worry about things falling out of the open-top side pockets (just keep soft fabric near these areas in the inside compartment, and you can get a water bottle in and out easily enough; get something hard like a laptop battery behind there and it’s hard to use these pockets. Also, if the backpack is full, it does not fit into the smaller plane overhead bins, and it takes up the entire area under a seat—the flight attendants are not fond of it but haven’t hassled me, yet. If you are not flying, it’s great.
