Extra clothing

"At what point does everyone else start adding in more 'clean clothes'?"

I was doing a 25-day trek in Nepal, so I had one synthetic t-shirt plus two spares. The spares never got used. Years later, I was doing a 20-day trek in Nepal, so I had one synthetic t-shirt plus one spare. The first t-shirt had to be rinsed, so the spare got used while the first one was drying. Unfortunately, the first one was frozen for three days which slowed drying.

–B.G.–

for a week long trip no extras, save a pair of socks- this are used to sleep in; if it's warm I often wash clothes mid-week

I typically wear shorts and carry a light pair of tights for wearing around camp in the evening/morning- if I need to wash my shorts I can slip into these

extra (unneeded) clothing was the first and easiest way to lighten the load- I even now have my wife convinced (that took a couple of years :))
