Moleskin Waistcoat.
From Brisbane Moss and Tailor Hoff.

This heavy (410 g/sqm) grade moleskin has been used by Tailor Hoff in Saarbruecken to make a single-breasted waistcoat. The waistcoat is made entirely of moleskin, even the back which is usually made from lining material. The back belt can be adjusted using the buckle. Genuine shank-sewn horn buttons and two front flap pockets. The striped viscose twill lining makes this garment particularly comfortable.

Care instructions.

Dry-cleaning is recommended due to the different fabrics. To remove the shine that moleskin acquires with age (moleskin is very similar to leather in this respect), brush the moleskin lightly against the nap to bring it up again.
