Ralph Waldo Emerson once said, “build a better mousetrap and the world will beat a path to your door.” Solo is hoping to do just that with a new strap for laptop cases promising a “no-trip” experience. The company says its Smart Strap bags come with a patented retractable shoulder strap designed to stay out of the way when not in use. Anyone who regularly carries a laptop knows how much of nuisance case straps can be.

The bags come in a variety of styles and materials including ballistic nylon and leather. They range in price from $60 for a laptop portfolio to $120 for a rolling laptop case. Solo bags are available at a variety of online and traditional retailers.
