Kevin Drum It's a relatively cheap bag, but it's worked well for me. amazon.com/gp/product/B006R239... I removed the brand badge off mine as soon as I got it so it would look cleaner.
Maciej Szlachta Thanks, I'm looking for that kind of bag for some time, unfortunately it is not so simple in Poland :P.
Maciej Szlachta Nice one, what is the name of it?
