The specifications and product care for the Half Neck Millennium are as per our Millennium.
The Half Neck has a very forward cut with and neck line area. The advantage of this style is that it causes no pressure in the wither area at all. It also offers added protection against rain running into the neck area.
There may be a small disadvantage for some horses with this style. There is a possibility that the half neck section may rub the horses mane. This is not experienced by all but may effect some horses.
