This bag was a perfect 3 day trip carryon. I packed enough for 5 days and still had room.

This laptop carry=on backpack was perfect for a 6 week international trip. It has three main compartments - a laptop compartment in the back, a middle LARGE compartment that zips out to expand, and a small front compartment for documents. All three compartments have lock-able zippers, and the body has adjustable straps on both sides to cinch it tighter and closer to your body. There are also a number of outside pockets and comparments: The front has a full size pocket and a small pocket, theres a water bottle holder on the side, and theres a secret compartment on your lower back. The lower back is also padded so its more comfortable. The straps can be unlatched and tucked inside to use it as a suitcase, and there are handles on the top and side. This was allowed as an underseat bag on a major american carrier. Roomy and comfortable! Also came with two packing inserts that I didnt use.

I have some big trips coming up and I believe this bag will serve me well. It’s a good size, appearing to be large enough for a weekend’s worth of stuff but small enough to fit under the airplane seat. It has lots of pockets and seems to be solidly constructed. If I had one nit to pick, it’s regarding the front pocket design. Assuming you pack the main bag portion full of clothes and things, you’ll need to utilize the two front facing pockets for most of your easy-to-access items while en route to your destination. The rest of the bag’s pockets are somewhat closed off, at least without unsnapping the side support/cinch straps. However, the two forward facing pockets are just slits, not allowing for the flap to open up more to see all inside. Also, inside the pocket could use some smaller organizers for items like pens, passports, etc, but it’s just one compartment for each of the zippers. This isn’t enough to knock down my score, but it provides room for improvement if the bag is ever redesigned.

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.

Exceeded my expectations! Perfect for travel with a secure place for laptop. Bought for trip to Europe but I will probably use as an everyday bag. Expands so you can fit a couple days of clothing and extra pair of shoes. Highly recommend! I purchased the cream color. Very stylish!

This is a really great travel bag! Its the perfect combination of an electronic bag and a weekend suitcase or carry-on. Its a good solution for airlines where you can only bring one personal item. I love the different combinations of zippered pockets. They really made great use of the space. It opens just like a zipper carry-on luggage. But it also can be carried like a briefcase or backpack to hold all your in-plane items like your phone, charger, laptop, wallet, book, tablet, and whatever else you are bringing. This is a really cool bag that I look forward to using. It is really easy to use. Its really strong. The stitching is nice. The zippers are smooth. Im so happy with this bag.

This is a great travel backpack, especially for the price. It has the ability to expand if needed to add additional items. Inside the main compartment is a tie down for clothes or other tiems. There are multiple pockets, including a secure pocket on the back which has plenty of room for documents, money, etc. There are two handles, one on the top and one on the side, which I think is so forgotten on other bags. There are times you just want to pick up the bag, and dont want to only carry from the top, or find that one handle, especially if you take advantage of the ability to store your shoulder straps in the pocket in the back. The material and the zippers are durable. The bag is relatively lightweight and water resistance. The description says it is waterproof. I hope I dont have to test that, but the materials feels like it will easily repel water. Other features - padded back, a more water resistant pocket up front, two front pockets that open from the top of the pocket and is located at the bottom, and one that opens from the side. Allows for great flexibility in how you organize your items. With most bags these days they include a USB connector on the outside of the bag. At first I was disappointed when I didnt see one on this bag. It has a small port for a cord to be slipped through. Actually that is much better, because as much as connectors change, being able to slip through whatever you need is probably better than a fixed type. I love this bag, and it will undoubtedly become my go to bag for travel.

Im very impressed with this bag. There is so much room and a pocket for everything. I have four kiddos and were traveling at the end of the month. I cant wait to use this. The quality is very obvious as soon as you touch it. It feels really sturdy.

Great quality and lots of compartments. I like the large zipper pulls, the number of compartments and the expansion. Also nice you can tuck the shoulder straps inside when not needed. Satisfied customer. The toiletry bags are a bonus.

This is a very spacious, well-made bag. It is great for long weekend trips, as a carry-on for plane trips, or a big work/school bag. It has lots of features, storage chambers, and it includes two accessory bags. Packed carefully and efficiently, you could travel somewhere for a week with this bag.
