60 days in the middle of a winter ARTEP. A combined Graff and Hohenfells trip :p
And 2 weeks in the middle of nowhere Arabia during Desert Storm.
So I was backpacking once. Went well over a week without a proper shower. ******** down to our next to nothings in the rain though so that helped.
Like a month
I'll often take 2 in one day !!!
Can't see how people can deal with not feeling clean and fresh.
