"Fair thee well" reducing clothing drag?
 

Although we have previously discussed that boat-tail helmets would be a safety hazard (try doing a shoulder check at 60mph) check out the faired rubber downhill skiing suit! The posture reminds me of a Ninja 250 duck?

Then there are rain suits for motorcycles that would reduce drag and cloth flapping. If you could withstand the jeers from the HD riders in their extremely high drag leather fringe...

This would probably be a bit hot on a sunny summer afternoon! :eek:

Walk into a hog watering hole while wearing this could git ya kilt!

If the leather fringe is in the right place it might be lower drag than a plain leather leg or sleeve. It will act something like a flat plate splitter, to damp the "flopping" of the vortices behind the cylindrical section. It's not as good as a rigid flat plate of course, but could have benefits over a smooth cylinder.
