This garment has been made with a fabric designed using the exclusive RRD "Holystic Technology 2" method that guarantees functionality, style and uniqueness of the product thanks to two components that, joined together, make up the structure: the shell, in extra fine stretch Merino wool, is combined with an elastic, breathable, wind and waterproof polyurethane membrane capable of ensuring a resistance of 5,000 mm of water column. Externally, it is in velvet with heat-taped seams.
