I swear by Swiss Gear nowadays. However, it's been several years since I purchased one. I don't know if they've maintained the same high quality.

But I had a Swiss Gear backpack that was fantastic, and it lasted me nearly a decade. It was originally purchased at a Target. It was versatile and I could take it anywhere. It had little grommets to pass-through earphone cords and such. It survived even through several washes in a washing machine.

Then at a thrift store, I found a Swiss Gear suitcase. It has wheels and a telescoping handle. It expands very nicely. I have it stored away and still haven't found occasion to use it.

I also picked up a Swiss Gear laptop bag with a "messenger bag" shoulder strap. These I found at Office Depot. It's really nice. It has a velcro fastener to secure the laptop itself. It has mesh pockets for all kinds of accessories. If I don't put in a laptop, it can carry documents, folders, or binders. It's been very durable.
