I need some help. Before this year, I was able to avoid commuting with my laptop most days. When I did need to carry it, I had a large pannier I could use. Well, got a new, small laptop (9x13 inches). Now when I put it in the pannier, there is too much extra space for it to be secure. I could add padding, but I don't want to carry anything that is unnecessary.

So, I'm looking for a different solution. I have been using a backpack, but I hate having it on my back in the heat. All the laptop panniers that I've found seem to be for larger (15 inch) laptops. Any suggestions?

Thanks!
