Rolling and Folding.

I suspect that many readers have already seen the above video. It may be one of the most useful things on the internet. Using this technique putting away the laundry has become a quick job of a few minutes rather than a tiresome chore.
Yesterday I came across the term “ranger roll” used to name an alternative to a sleeping bag. Not a term I had encountered before. It turned out to be an alternate name for a poncho and liner used as a sleeping system. A websearch on “ranger roll” in fact turned up something quite different:

Rolling clothing this way may be old news to many of you. If, like me, you had not encountered it before there are a number of webpages and videos. Once you have seen how it works for towels and tee-shirts you can probably work out how to roll most items. Some users suggest items may be rolled tighter if rolled on a hard surface. Some items may be more compact if folded flat. It will also depend  on the space where you need to stow something, so experiment.
I realized that I had encountered the technique before. My mother used to “marry” socks by rolling them up and turning over the cuff. As an adult I realized that this was a complete waste of time. Dump your washed socks in a drawer and grab the first pair that look similar.
The ranger roll method is worth trying if you have to pack items. Remember that items such as sleeping bags and down jackets should not be stored for long periods tightly rolled.
Many items of outdoor equipment that you buy come in their own stuff sack. Like me, you have probably unpacked the item to examine it and then found you cannot fit it back in the sack as neatly as it came. Using a ranger roll it may be possible to pack the item without using the sack. Either save weight by not carrying the sack or put the sack to a more useful purpose.
