The Greyback Parka boasts duck down fill, housed within a lightweight synthetic cloth. This combination of natural and man-made fibers work together to deliver exceptional heat retention, water resistance and supreme comfort.

The garment shell is produced from a diamond weave micro rip-stop backed with a thermoplastic membrane; the latter coating is engineered to allow for the free passage of water vapor, making it breathable, however does not allow water droplets to penetrate its surface.

The diamond weave gives the jacket surface a
unique iridescent look, a near-shimmer, making it wholly more dynamic and unmistakably MA.STRUM.
