Recently I discovered a technique used by American army officers when they pack their kit. This is know as the ranger roll. I have tested it and it works. You are able to maximize your space within your suitcase whilst keeping your clothes fresh and wrinkle free.
Below is just one video about a ranger roll. For more just search this technique. You can roll almost any clothing item.
This video was found on YouTube and does not belong to me.
Incredible. Nice. I'll give it a bash. Although I did not do this as in the video, I packed my army bags and my hiking bags in a similar way.
