Bergmütze (mountain cap) mid war type.
Bergmütze made of early fieldgrau wool, best availabe reproduction buttons from EU, grommets for air vents are original German WWII , 100% cotton twill taupe liner, sweatband made or real leather from Polish tannery , most correct buttonholes (cut before) and hand stitched high quality T- form insignia.
I suggest to choose parcel budget/priority for this type of cap.
