Traveling light demands attention to detail. I found some lightweight and inexpensive carabiners that have proven surprisingly useful during my last few years of travel. I always have one clipped to my backpack.
Here are some examples of how I use mine:


There are a million other uses such as:
- Clipping dirty shoes or sandals to the outside of your pack
- Hanging things up to try
- Clipping your gear to yourself or to a luggage rack as an extra layer of theft prevention while you are sleeping on a bus
- Use to reinforce your fist if you need to punch somebody
- Give as a small gift
