Vidrio 15 is to me very slippery, wear these alot, even sleep in these. Feels very nice against satin sheets! Also found out that capri 8 by transparenze is a slicker hose also, super thin, but feels nice when legs rub together, I wear every day to work a pair of Filodoro Aurora 15's sold by Shapings. These have a very silky feel on shaved legs, and they are comfortable. The largest size(MX) does not have extra panel, just feels great.
