40L Waterproof Travel Backpack for Women & Men - Large Carry On Backpack for College, Business, Work & Outdoor Adventures - Durable Personal Item Backpack for Air Travel, Commuting & Daily Use

I’m really happy with this purchase. I was skeptical because it was so inexpensive, but it seems pretty durable thus far. I’ve taken it with me for 5 flights, 3 trains, and 4 hotels and it has held up. I am someone who packs TONS of stuff when I travel. I typically check a suitcase, but I was able to get by on a recent trip with just this bag and a small carry-on rolling suitcase, so I didn’t need to check any bags.I ordered 4 similarly-sized backpacks from Amazon and kept this one.Reasons I kept it:*Holds a ton*Main large section can be accessed from the top (helpful when you’re sitting in your seat on a plane), but can be opened all the way for easy access and packing. I have another large backpack that opens like a clamshell (similar to a hard-sided suitcase), and I find it hard to access items during a flight.*Padded quick access pocket for laptops and iPads - easier for TSA security access, gives support and structure, easier to carry on your back*Straps are fairly comfortable and has a chest strap for extra support*Trolley strap thing on the back to attack to your rolling suitcase - it’s amazing to me how many travel backpacks lack this feature!*Quick access security pocket on back of backpack - great place to store a passport or wallet for easy access while keeping it safe*Waterproof pouch - I didn’t think this was a feature I needed, but it ended up being useful on the first trip - was able to throw a wet bathing suit in there and get on a train. I think it would also be useful for someone who didn’t want to pack a separate waterproof toiletry pouch - you can just pack your liquids in the waterproof pouch and protect the rest of your belongings from any spills.*Exterior side pockets - again, I’m surprised at how many backpacks lack an exterior pocket for a water bottle. This one has two. I often use one pocket for my water bottle and the other pocket for a curling iron that is still warm (not hot enough to burn anything, but warm enough that I don’t want to pack the curling iron inside of my suitcase)*Comfortable padded top handle*Comfortable padded side handle*Compression straps on sides to make the bag a little smaller*Tons of internal pockets if you’re into that type of thing*The light gray interior makes it easy to see items inside of the back - not sure if this is on all of the colors or just the cream or lighter colors.A few drawbacks:*I got it in the cream color because it matched my AWAY rolling suitcase and I felt it was a little less boring and masculine than the black color. I like the color, but it does get a little dirty. I haven’t tried to clean it. I expected this with a cream backpack, but don’t get cream if this will bother you.*The compression straps are slightly annoying at times because they flap around if they’re not buckled and I don’t want to always be buckling and unbuckling the straps. This is a minor inconvenience, however, and I appreciate the compression functionality when needed.*I almost think there are TOO many internal organizational pockets, but I just don’t use a bunch of them and it’s fine. Probably better to have more pockets than fewer pockets! I think if you’re someone who just travels with a backpack and uses the pockets for toiletries and stuff, then they might be useful - but I tend to travel with a separate toiletry bag and don’t need all the extra pockets for things.
