I'm looking for a replacement for a pair of magic shorts.
About a decade ago I bought a pair of clearance sale board shorts (I think Speedo was the brand) that had magical drying properties.
In the sun they got bone-dry in about ten minutes, indoors they dried in a couple of hours. In contrast, my new (Quicksilver Manic) polyester shorts hang all night in the shower and are still damp the next morning.
The texture was sort of rough and crinkly, and thinner than most swimsuits I've worn, but still opaque. They had no mesh liner. Are there modern board shorts that are made of similar stuff? And -- what is it?
