Kono Carry on Backpack, 16" Airplane Approved Under Seat Travel Backpack for Men and Women, Waterproof Lightweight Daypack for Flight 20L (Black, Small)

I bought this to use as my "personal item" for an airline trip, which gives you an idea of its size. It fit nicely under the seat and held A LOT of stuff. I also used it like a purse while I was traveling and sightseeing - it's 3 zipper compartments made it easy to store my packable raincoat and hoodie but also to find my attraction tickets and hair ties etc... I also bought it because the description said it was waterproof, but I never had to put it to the test so I can't comment on that feature. The side straps allow you to compress it if you only have a few things, and expand to hold a lot more. It held up great through a 2 week trip with all day daily use. Very pleased with this purchase!

Bought this for domestic flights, good value, it travels well with enough storage for the essentials. Zippers work good, it fits good with adjustable straps and the style looks good.

It's a great small backpack with great storage But we were using this for carry-on flying to Europe, so we ended up using a different backpack that we had ordered because it had exterior water bottle holder pockets. Ended up returning this since we won't be using it as much as the other. If a water bottle holder is an important to you, then it's a great sturdy backpack.

I bought this for my husband in black and ended up loving it so much that I bought one for myself, too. It's just a solid, well-made bag that's great for air travel, especially when trying to meet under-seat measurement requirements. The extra pockets are actually useful, but don't add to the profile of the bag or take up space I need for "stuff". We bought them for travel, but find ourselves grabbing them whenever we need a little backpack for running around.

I was very careful to purchase the right size personal item bag for my once in a lifetime vacation flight.It was great for that purpose. I was able to pack ALL my toiletry items along with my laptop computer, charging cords, and a couple of books in this bag and it still fit under the United Airlines seat. But it was heavy!While on vacation, I used it as a purse. It worked so well for that purpose, that I kept it.Great value. Great storage capacity! Plus, many pockets for items normally carried in a purse: Ziploc bag for odds and ends (lip balm, feminine hygiene, asthma inhaler, dental floss, etc), wallet, phone, checkbooks, water bottle, sunglasses, keys.And because it's tall and narrow, and straps control its depth, I can easily access all these items in an upright position and put them back where they belong when I'm finished using them. Plus there's room to stow an extra sweater and hat without it bulking up out of control.Plus it's 1/5 the cost of the last purse I bought! Thank you, Kono!I'm not sure why it's rated for security features. It's just a backpack with a zipper. There is no lock. So I'm just reading it a three for that, but I don't consider that a flaw at all.

My son & I each had one of these that we used on our flights between Madrid & Dublin. The bags were great & we had no issues taking them on Ryanair. They held a lot while meeting the European "small bag" standard. I packed each bag with a pair of sandals, two 14x9 inch compression packing cubes, and a small toiletries bag. (Compression bags held all our socks, underwear, shirts, PJs, pants, & raincoats. We wore our boots, sweaters, & jeans on the plane to save room.) With all that, there was still additional room in the main compartment to include a few loose items like extra socks or charging bricks. I put our passports in the front (diagonal) pocket & snacks/phones/wallet in the middle pocket. Since the two main pockets open 180 degrees, it was really easy to access what we needed at any time. We were able to make it two weeks out of these bags with one laundry stop in the middle. The zippers didn't seem super sturdy so I was careful with them, but ultimately nothing broke & the bags served us very well. I would recommend them.

I like this. Lightweight and my things will fit in this perfectly when flying and fit well under the seat.

This was a very good versatile, comfortable, travel ability pack with storage capacity for personal items, shorts, T-shirt, ID, travel documents. Has huge strong straps & smaller ones on the size to squeeze it together for more strength. Weighted about 11 Lbs packed. Good buy for the money.
