Notebook Carry Bag

I'm looking for a bag like everyone has their laptops. A soft carry bag easy. But to accommodate a laptop 20 "screen. Without it there is a large piece of heavy baggage.

Try some of them, you may be a 20 incher squeze in them.

Most office supply stores should have them (Office Depot, Office Max, Best Buy ...).
You can also search on google "product search" keywords such as "laptop case 20''lumia¨re and find one that seems cheap and decent!

Good luck!
