Super Soft, Sweat Wick Bra Liner, 70% Viscose & 30% Cotton, No Tags, No Seams, Size: XL

Never bought when I had breasts and no need staying flat now, but how about something more like this? BTW I hated underboob sweat and the rash I’d get. https://www.amazon.com/dp/B01IGXENK0 Scroll through images for a better idea. I like bamboo fabric for sleeping in hot weather especially but also so soft.
