From the link I clicked on the Target website I thought these were merino wool I entered the page from here: Woolmark Winter Thermals - Target Australia a page dedicated to Woolmark and Merino Wool
This is the description for the MAXX waffle knit long johns
Let Maxx's great range of thermals keep you warm this winter. Featuring Silver+ technology to help inhibit the multiplication of odour-causing bacteria. The unique air pockets in the thermal waffle fabric trap the body's natural heat, forming a warm layer next to the skin. These thermal long johns are constructed from soft, breathable cotton blend fabric and have an elastic waistband for added comfort, a fly front opening for easy wearing and rib binding to help prevent body heat escaping.
no mention of wool.
NOT HAPPY TARGET!!
