Volt: spandex = tight underwear, pretty much a GLOVE.
Anyone wearing a spandex constume would have a big bulge. It's just that as kid's we're use to seeing batman, spiderman, superman with a FLAT like tighty-whitey apearance in the crotch area and so when we see the REAL life spandex effect we think "wow".
Take off your pants, throw on some spandex shorts from "the sports authority " and look inthe mirror. My point exactly.
