This garment is made thanks to the exclusive RRD "STITCHLESS DOWN FABRIC" method which prevents the feathers from coming out (90/10) thanks to the use of a tubular stretch nylon fabric. This technical feature allows the garment to be extremely comfortable due to its elasticity and lightness. The details of the sleeves are made of Lycraᆴ (95% nylon and 5% spandex) in "Ottoman" weave.
