Jack Wolfskin Bonnet Pergamon

With the PERGAMON beanie style windproof knit cap, your head always stays warm when you go to work, out on the town or with friends. It is made of POLYLANA yarn: a lightweight woven synthetic fiber that uses recycled PET flakes for its manufacture. As a lining we used a soft and windproof TEXASHIELD fleece that keeps you warm while letting your scalp breathe.
