So what is the difference between Primaloft and the polartech material? I can only find Primaloft in outerwear and polartech material in base layers. Surely there is more than that??
Polartec is a brand that makes a ton of different fabrics from outer layers all the way down. Primaloft is makes different products too but 99% of the time it is used by clothing manufacturers as a lightweight, lofty insulation material, which means it is in mid and outer layers.
