KAKATravel Backpack,Carry-On Bag Water Resistant Flight Approved Weekender duffle backpack Rucksack Daypack for Men Women (Black upgrade)

I never used it but I have witnessed a lot of my co-workers who did. It holds heavy books and it is true to its size. A large is extra large so you may want to consider a medium.

Functionality is excellent!

Use this bag as my every day carry from home to work for the last 4 months and it’s held up rather well. My only complaint is the way that you have to keep the back flap rolled and tucked on top with the Velcro, I wish it could be completely removed if you’re using as the back back.Has plenty of room to pack a couple days worth of clothes when traveling, or bringing my clothes home from shift. Compartments are spacious, but could have more subdividing. Laptop pouch is great and protects my MacBook even if I drop my bag.

Exactly what my son needed for his traveling for work. He has to travel every eight weeks and needs only two nights of clothes. He also has to carry his laptop and other electronics. This bag has a full individual laptop compartment that is fully padded on both sides. In another zippered compartment, there is a separate sleeve for a tablet. There are additional zippered compartments for storage space.He prefers only carrying one bag and this one is large enough to carry everything he needs. He really likes the fact that he can adjust the bag for his current needs.In the airport, he prefers carry the bag as a backpack. All he needs to do is unzip the cover and roll, then adhere to the top and attach with Velcro. One other nice feature is the flap over the top zipper at the top of the backpack. This helps secure the zipper so others can't easily get in the pack when you have if on your back.When he is actually inflight, he prefers closing the flap which hides the backpack straps. Now the straps won't get caught on your legs or the seat of the plane.When in the side briefcase mode, the bag can be carried with the included shoulder strap. It's easy to carry and looks very professional. One problem in this layout is the Velcro is left exposed at the side of the bag. The manufacturer chose to use the rough side of the Velcro and it is exposed. This Velcro seems to adhere to anything that gets near. Can be a nuisance.It's a very nice weekender bag that meets a variety of needs.

This bag held my clothes and essentials on a 30 day travel through Thailand. Though it is a bit small, I packed it to the brim. It handled the pressure and over-filling fairly well, though one pocket did rip open about halfway through. It was an interior pocket so it wasn't detrimental to the bags function. I was pleasantly surprised with its durability and felt confident with the straps. While on the trip I had 3 other bags that the strap broke, and this one held up just fine.

Convertible, made well, lots of space and cool features. Highly recommend

Very large back, cavernous in fact. Not a lot of organizational features just several large pocketsHeavy when emptyIt does convert to a duffle but there is a zippered cover to hide the backpack straps when you do this, but when in “backpack mode” it has to be rolled up and sits on top of the straps so looks oddNot much “structure” so when you put it done it just collapses into a pile versus holding itself upThat said a pretty good value and if you need a travel bag with a fair amount of storage that can still fit under a plane or train seat it works

This is an amazing backpack. I am not a paid reviewer. I've only written a few reviews, ever. But I felt the need to talk about this backpack. I purchased the KAKA backpack about 13 months ago. I had recently lost a leg in a shark attack (check out Nat Geo June 2016). Prior to the attack, I traveled a lot and led a very active life.Even though I only had one leg, I didn't want to give up my active life. I started making a set of prosthetic legs for each of the activities I loved. I made one for skiing, rock climbing, surfing, and trekking. I needed a way to carry these various legs and spare parts when I traveled (also my laptop, and clothes). That's when I purchased the KAKA backpack. This backpack has been my companion for the last 13 months. It's been all over the world (China, Japan, Mexico, Cuba, DR). I've flown over 120k miles with it.The backpack fits perfectly in the overhead compartment of an airplane. The weight of the bag is well balanced. If you've ever carried a backpack for a few miles, you know how important balance is. The straps are tough and they don't dig into your shoulders. The bag is sturdy. When it gets dirty, I just hose it off.I only had one problem with the backpack. One of the zippers for the main compartment fell off. But since there were 2 zippers for the compartment, it didn't really matter. I let the company know about the problem and they immediately sent me a new backpack. These guys are great.

Looks great, and fits a takedown Ruger nicely. Very comfortable bag for long bush walks. Wish the main side zipper was about 1 inch longer however, for my application. Has a nice pouch on the side to carry a water bottle.

I really like this backpack.

Tiene buen tamaño para llevar como maleta de mano y se nota robusta. Sin embargo me llego incompleta, le falta la correa para poder llevarla al hombro. Por eso no le pongo las 5 estrellas.

Great design, well made, lots of pockets, strong, multiple carry options

This bag is totally impractical. To the extent that I returned it. Zips are not smooth. Getting the laptop in and out is very difficult and if you have other items in the bag almost impossible. The pockets are very awkward to get into. Overall it is very poorly designed.
