This 40L travel backpack from Sinaliy is a well built and very comfortable bag with LOTS of pockets and storage, this is an approved for flying as personal item so that is a big plus ++. you can expand the bag to get more 1.5 of room or 5L in volume, you get a designated protected space for a laptop up to 17 and lot of small pockets, you can even stow/hide the shoulder straps into a designated pocket so you can use the bag as a carry on. this is a very durable lightweight and water resistant bag, very recommended to have and for $39.99 at the time i made this review, its a bargain.

Very impressed with the quality and space this bag has! The material is strong and feels durable, the pockets and expansion of this bag make sure I can fit everything I need, the buckles make everything feel secure, and the laptop pouch is big enough for my big laptop. The padding on the back and shoulder straps make it comfortable for travel, and I like that the straps completely detach and can be zipped away. A nice touch. If you need a nice backpack or work bag, Id recommend this one! I think youd be really happy with it.

Lots of pockets, holds a LOT, and is cute! Love that its expandable and the strap to go over luggage!

I absolutely love this bag! The quality of the material feels pretty good, and I love all of the pockets it has. I also really like the compression capability which will come in handy for plane rides that have smaller than ideal overhead bins. What I dont like about the bag is that it only has one internal zippered pocket. So, while ideal for travel, its not great for school/work use. My previous bag has a few internal zippered pockets for documents or other small items, but this bag is missing that feature. It was supposed to come with two of the clear zippered pouches, but I only received one, so I took off a star.

I bought this for a 5 day trip to Chicago and it fit everything I needed! I flew with Frontier and it passes as a personal item. Its well crafted, sturdy, cute...my new favorite travel item!

I’m very impressed with his backpack. It’s the perfect size for carry-on and it’s expandable. It has lots of pockets and it’s a very clean. Look the outside pockets have a side zipper. Also, you can disconnect the straps and hide them in the zipper compartment which turns his backpack into a sort of soft briefcase. It feels very sturdy and not cheap. The zippers are made very well. Don’t feel like they will break. It also has a front strap to put over your rollaway luggage.

Loved the color just as described. The quality of the bag is worth the price. I have not used it yet but can’t wait to test how much I can pack in it. There are definitely enough pockets and love how versatile it is.

This is a very well made backpack that is durable and perfect for travels. There are plenty of compartments for all my travel essentials. LIKES + Size + Well Made + Compartments (including wet) + Padded Shoulder Straps + Waterproof + Value DISLIKES - None

Backpack took me to Ireland for a week with all my clothes and toiletries, but not for an extra pair of shoes without the expansion. Utilizing packing cubes for organization, was easy to pack. One trick on packing (used for the return) was I packed the bag when it was fully expanded, then I zipped the expansion back down to compact the bag. Small pocket on the very front of bag was good for quick access to small papers/passport. The side sleeve pocket in the front where the zipper goes up and down I couldnt find a use for. The white color shows signs from the trip as it scuffs. Can see some of the stitching of the zipper as its expanded so not sure if the seam will fail at some point from that.
