When my girls were little, they liked to put on all of their dresses at the same time. It would be so funny to see them bundled in stacks of clothes. They would peel off a layer at a time until they were down to just one dress.
We went shopping for our Mt. Kilimanjaro layers the other day. By the time we reach the summit, we are supposed to be wearing at least four layers of clothing - a base layer of long underwear (top and bottom), a second, thicker layer of long underwear (top and bottom), pants, a fleece jacket and finally, waterproof jacket and pants. No cotton is allowed. That doesn't include socks, boots, hats and gloves. I have heard that on the final summit day, hikers don every stitch of clothing they have brought with them. I hope I can walk!
