Are you really a light traveler, or - should I ask - are you a really light traveler? Tell us how light you can go for a trip of four nights or more. I’ll go first: just over 10 pounds (including day bag/personal item) for five nights, trans-Atlantic to Europe. And this summer I did sub 15 pounds for 11 days in England and Scotland - including day bag/personal item. I don’t know if I’ll ever beat Tim Ferriss’s 10-pound kit which includes a computer. I’ve resolved not to buy another laptop until I can afford a featherweight (three pounds our less).How to weigh? Well, you can step on the bathroom scales with and without your bag. Even better is a luggage scale (above). Mine came from Target. It actually has a tape measure built in.
