Which side should face the insulation on with calendered fabrics?

All our calendered/downproof fabrics will have matte and shiny sides as a product of the calendering process. It is recommended that you put the shiny side towards the insulation (down, Primaloft, etc) and the matte/dull side facing out.

  • Can you elaborate why it is recommended to have the shiny side facing the insulation? Besides appearance, is there some material property that differentiates the two sides?
