Thermal tights not leggings tights. When it says "outdoor" it means camping or something.
Wear with a long winter skirt or tunic top and boots as they have a gusset crotch, not a central seam. Looks like a fine knit rather than t-shirt fabric, but not see through. The brushed backing feels so very soft and warm.
You could get away with wearing them under trackies if you're cocooning in Melbourne's winter. Don't forget you will eventually have to wash them. ;-)
Thicker and *much* better quality than the thermals you find in disposals. (Would make an awesome donation for people who are "between homes.")
Excellent quality and the suppliers are really nice to deal with. They were delivered the next day. Great service.
