One thing I do, and it looks a little like Shrewie might also do the same, is to double-pack some things. That is, to put one container inside another, to hopefully prevent leakage. But the only thing I actually do that with is skin ointment and it happens that I use that more than anything else, at least in cold weather. The tin container it comes in gets greasy all over, so I put it inside yet another tin container, which mostly solves the problem. Other things, like sun block, go in little flat screw top plastic containers which never seem to leak. I've never used anything that had a nozzle unless it came that way and I don't have anything now that has one. This is not to say that none of my outfit doesn't still have issues, minor though they may be. Personally, I find that a piece of soap (after it's been used) is as difficult to pack as anything else, although it's way down on my list of problems, probably close to the bottom, in fact. Anyone use an all-purpose soap or detergent, good for washing your body, your clothes or your cooking and eating things?
