This a men's vintage Woolovers dark green warm thick knit 1/4 zip high neck Wool-mix jumper or pullover in a Size 2XL. It has a small piece of darning on the front in the middle of the chest, (see photos), and also a small hole on the hem at the front.

I live in Little Waltham near Chelmsford in Essex and you are welcome to collect if you live nearby.
