The wax keeps what the advertising promises: Outdoor clothing (not only of FällRaven also from normal cotton) is water resistant; Insects may no longer eat by lightweight fabrics through lightweight fabrics with unpleasant bites. After washing, easy to apply by rubbing. First, then the clothing looks quite strange. The disappears immediately when going with an iron over it. With repeated order to generate absolute water tightness, the surface appears shiny satin. This one does not need my opinion. (Even with three days hiking in the mist / rain on Mount Kenya the simple protection was perfectly adequate, even on the "pseudo-Treckinghose" my girlfriend)
