Heat retention is about how well a fabric acts as an insulator by trapping air and slowing heat loss from the body. Fabrics with good insulation have loft or texture that creates air pockets, which reduce heat loss through conduction and convection. That’s why thick fleece, wool, or quilted materials feel warm—they keep the warmth inside by keeping air trapped. So the property described is the fabric’s ability to retain heat or insulate. It isn’t about how heat moves through the fabric, care instructions, or wrinkling.
