Wow, where to begin.

MSR Titan kettle: pot, cup, and bowl.
Prolite 3 pad and chair kit: doubles as frame for my Virga pack, and as sleeping pad and chair in camp and at lunch.
Dromlite water bag: inflated with air (or filled with water) as a pillow
W/B rain jacket and pants: wind garments, extra layer of warmth, and long pants (since I wear shorts.)
Long john bottoms: extends shorts to long pants in cool weather.
Tent or tarp: lunchtime shelter
Down jacket, long johns: extend range of sleeping bag, if necessary.
Packtowl (hand sized): washcloth, pot holder, towel, etc.
Hiking poles: hiking, tarp support
MSR Ground Hog stake, 30' parachute cord: spare tent/tarp stake, clothesline, extra guy lines, bear bag hanging, and (my favorite) wrap the cord around the stake and you have a toilet trowel with a padded handle.
