In case you haven’t heard of these two types of hoods either, the difference is as follows:
Two-Piece Hoods
You’ll find that most casual wear or athletic-designed hoods such as the ones High Schools often buy for their sports teams are designed with a two-piece hoods. This is because they are cheaper to produce due to the fact of less fabric and seams.
The Seam
The two-piece hood will usually have the seam located at the center back of the hood, starting at the base of the neck and coming up towards the top of the head. This simple design saves on fabric and time to produce the hood.

Three-Piece Hoods
These hoods are more commonly found on higher-end hoodies, jackets, and coats. The seams run from the back of the neck all the way to the front of the hood and are located on either side of what would be a centerline.
The Seam
With the seams running the whole way and the added fabric (three-piece) the hood is more form-fitting. As a result, the hood will be much more comfortable and stay on your head better than the two-piece design.
