Endura tights, in which I discovered a potentially embarrassing hole on the Whitby ride. I've since obtained a marginally[1] more Kim-shaped replacement, but those have turned out to be wholly unsuitable for lying down on the job, on account of a lumpy waist band and knobbly back pocket.
*sigh*
[1] Tight around the quads, rather than about 12" too long. Does nobody make cyclist-shaped cycle clothing?
