The pattern works pretty well in the Mojave Desert and Chocolate Mountains in California. When I went to NTC back in 1993 my unit used them and they worked pretty well. Granted they were hot as hell but they worked in that climate. We switched out from woodland to choc chips and had to turn them back in unless we wanted to buy them. The new South African pattern is a Choc Chip knockoff with some green in it which probably works well in their region.
