Pak Chong Khao Yai is a GI name, not a separate variety. It is Monthong grown in the cool uplands of Pak Chong by Khao Yai National Park, famous for an unusually faint aroma, which is why it gets marketed as the 'non-stinky durian'. The red upland soil and mountain air are credited with the restrained smell and a dry, fine, barely-fibrous flesh that is rich but not cloying. Registered as a GI in 2021. Note that this is terroir Monthong, not a new cultivar, despite some press calling it one.
