Hold on, don't let your imagination get the better of you, SWIX Skin Impregnation has nothing to do with sex but everything to do with keeping your skins ice-free and gliding smoothly (think of it as DWR). Skin Impregnation is a long lasting, fluoro-free treatment that helps prevent icing (glopping) on your climbing skins when climbing through the freezing level and helps prevent water and dirt buildup.
