[1] Baja jackets are made with a variety of different materials, often cotton, acrylic and polyester.
The jackets tend to be somewhat waterproof and fast-drying, making them more suitable for the elements.
In recent years, they have been adapted to simply become hoodies with some alterations like a zipper running up the middle.
Because the striped pattern resembles a Mexican sarape, the Baja jacket is sometimes referred to as a poncho, but the two should not be confused.
