Toxic Smell

These are great caps and I have used them for years - work well for driving because no brim. HOWEVER, the caps I received in this last shipment (I seem to lose them regularly) have a VERY toxic smell. I have smelled this before and believe it is the black dye they are using in China - where there is very little consumer/environmental protection. I have returned an office chair because of this smell - no matter how long I left it outside to outgas, the toxic fumes would not go away - likewise a Grizzly sleeping bag more recently.I am letting these hats outgas in the mist for a few weeks and will probably wash them to see if I can make progress.Very disappointed.Greg
