Many of our customers don't like to iron, so they look carefully for garment care information related to ironing! These symbols are actually quite easy to figure out. Cool, warm and hot iron temperatures are indicated by number of dots. The more dots - the hotter the iron.
Of course the X through the iron means DO NOT IRON...and this is the one that some folks look for!
There is also an icon with an X through the steam which means that you should not iron the garment with steam.
