Airbac Transit Laptop Backpack

I wanted a backpack that will support my back because I carry so much stuff. I was planning on buying a rolling backpack but I didn't have a good experience with them lol.

Anyways I came across these types of backpacks on living social but I found this one much cheaper on amazon lol. I decided to try it out because of its "airbak technology".

There is card board in the backpack, I am assuming its to keep the backpack up right and the air bag on the bottom of the bag and bottom half of the back. So far it's really great, but its not for me. The size in the picture looked big and I thought it was going to fit all my stuff. (I guess I should've look or research for the size of this backpack lol)So this is not for people who carry loads of stuff on their back.

Ideally, this backpack is for people who carry an average or less amount of random stuff, not too heavy and not to light, (books, laptop, etc) Even though it didn't fit my things, I decided to test it by putting an average amount of what most people would carry. Well it works, it keeps your back straight and it does feel like you are carrying half the weight.

So if you are carry like 20 pounds or less on your back, I would say get it but it's up to you.

As for the airback technology, its just a bag filled with air at the bottom half of the back. I have heard that it may deflate but if you have the sport ball pump, I think that will work, although I am no sure. The hole looks a little bigger that a ball hole.
