My Altura Night Vision winter tights have gone funny.i mean it looks like when you have had a real good sun tan and your skin starts to peel off,you can brush it off in small flakes.Well the cloth seems to be shedding it's skin sort of,you can brush off small flakes in very big patches.I think we must have used some form of washing powder that has broken down the thermal coating if that sounds right.Anyway i have just washed them by hand to see if i can make it look better.Might be a walk to Aldi before they sell out of xl thermal tights.
