The Swiss are kind of like the red-headed bastard step-children of Germany. Kinda. Actually, that might be the Austrians. Anyway…..
From the New York Times:

In recent years, it has become fashionable for a growing number of Swiss and some foreigners to wander in the Alps clad in little more than hiking shoes and sun screen. Last summer, the number of nude hikers increased to such an extent that the hills often seemed alive with the sound of everything but the swish of trousers.

Mr. Hepenstrick, 54, is an architect who loves to hike in the altogether. In winter, he said, he has hiked for hours in temperatures well below freezing, though he does concede the need for a hat and gloves.

And a thimble, amirite?.
